Vertical? The Earth's Magnetic Field?!?! 

I'd love to see a time-lapse showing how it changes over time. Something like that might need to span decades though...

proof the earth is neither round nor flat it is two halves of a sphere, held tightly by the tape running across the equator

A sphere magnet and a protractor are a lot more inexpensive than that gauss meter but apparently just as accurate. Thank you!

2:25 *slaps top of table* this baby can hold so many magnets on top if it

I'm surprised a compass even works in your house!

WoAH, this satisfied all of my precision measuring itches, and when you did the earth's core demo it gave me a new sense of scale of our world.... now thats a big magnet in our planet.

I swear i've learned more so far in my adult life watching youtube than i did in 12 years of grade school.

I think there was a few of us with Morty in our heads testing "absolute level" during your video. Great stuff who doesn't love magnets, I truly enjoyed my first Brainiac vid, looking forward to more.

Most android smartphones also have a xyz magnetic/hall effect sensor. Type *#0*# into the telephone, click sensors and scroll to magnetic sensor. But of course, not as accurate as this meter.

It looks like the Teslameter is actually running Android.

hmm, it's almost as if the Earth is round and the magnet is pointing through the Earth toward the poles. LOL

Stunning demonstration, thank you. I never even knew a Teslameter existed but now I want one more than oxygen.

By far one of the most informative videos on the Earth's magnetic fields. I'll attempt to put this knowledge to good use.

I had myself observed this inclination of the Earth's field, and I often demonstrate it to friends and to random children using my collection of neodymium magnets. I find it easy to show with fair precision using 1.4"x1/4" cylinder magnets. I place 6 of them end to end, and capture a human hair between the two middle magnets. Suspend that from a doorway with a bit of tape, and the composite "bar" magnet will always find an orientation to magnetic north, including the vertical tilt.

I tried a similar experiment, but it all went South!😜

another fact. northern and southern hemisphere have compasses that are calibrated differently. so the needle is balanced properly

Always interesting and educational. Thank you!

This is why the south end of a compass needle is counterbalanced, heavier than the north side of the needle so that the north end of the needle is not pulled downwards too much, preventing the compass from being able to move freely. The opposite is needed for a compass to work in the Southern Hemisphere. Just a day or two ago I was responding to a flat earther who said that compasses prove the Earth is flat. He knew about the near vertical magnetic field and I did not so I educated myself on how and why compasses work on a globe. That is when I learned about the counterweighted compass needle. I have learned so much from arguing against flat earth conspiracy theorists. As frustrating as it can be, I have learned more about our planet, space, gravity, momentum, scale, astronomy, reasoning, logic and more in just one year of debating them than I ever learned in my 40 years preceding. Finally I realise that flat Earthers are good for something! Your video on Earth's magnetic field being uploaded today is a nice little synchronicity too!

This is an excellent video, and it's amazing that this is pretty much the only demonstration of this on all of RU-vid. You deserve every monopolized view you get, sir!

That last demo cleared everything up very quickly!

Although it makes perfect sense, I never really thought about this. I always thought of it as the classic image of the flux lines coming out of the poles. Thanks for an interesting start to the week. Thanks also for a year of enlightening and entertaining videos. I'm keen to see what else you will show us with your new toy.

So the magnetic field isnt.... flat!!

Glad to see you're still just as enthusiastic about this channel as you were when I found you years ago! Keep up the great content :)

LAKESHORE knew that you would be one user that will truly LOVE that awesome bit of kit, treat it like a puppy, and display it properly.

So awesome to see a Danish science channel of this quality. As a future physics teacher I will without a doubt use your videos!

There are rod-shaped bacteria which build a little chain of magnets inside themselves. The magnets give them mostly a up-down orientation, so they can efficiently find the sweet-spot oxygen concentration in the sediment/mud they live in. That's useful for them because they are can only survive over a pretty narrow range of oxygen concentrations (too little means no respiration, but too much is toxic). Anyways, yeah... Unless you're at near the equator, the Earth's magnetic field is mostly up-down. PS: Nice way to do an advertisement. I want one of those teslameters now ;)

It is absolutely fair to say , You are the easiest smart person to listen to . Very informative video with great editing . Thank you . I hope to see you above 1M subscribers before 2020.

Cool channel as always. Glad RU-vid started recommending your videos again. Subscribed!

Just as I was feeling the most depressed of the new year to come, my Danish hero springs into action and uploads a new video. Amazing as always! Keep it up :)

I can officially say that I am watched every single video of yours from 2018 from IRAN :-D and I am proud to be a subscriber of yours , you have taught me and my friends many interesting subjects and has been the reason for many fascinating arguments and discussions , thank you so so much for all the hard work that you have done this year and I can't wait to see your amazing videos for next year I can say this with confidence that you are the best Chanel on RU-vid thank you and I wish you a wonderful year ahead 💓🌷😊

Cool experiment. Glad I stumbled across it. And good for you for giving the Teslameter to a good home. That's a grand gesture, even though I'm sure you don't have a ton of use for it. But giving to a real scientist instead of selling to the highest bidder is a really cool move.

That’s an awesome piece of equipment. 35 Teslas!!! A new record of 45.5 T was just created with a superconducting magnet just last week. Though, measuring is easier than creating a strong magnetic field, but being able to measure micro Teslas with precision with the same probe is impressive.

"Do you want to experience true level? Do you?!"

Probably one of the least dangerous and least visualy impressive video you've done. But certainly one of the most awesome from my point of view. Thanks and well done !

From my understanding, all Magnets pull towards a huge Iron deposit under or near Hudson lake. This is why there is a declination constant when converting Magnetic north vs Grid North/True north. This is from what is was being taught to us in the Military and traveling the world. For example, in Germany the declination constant was somewhere over 20 degrees west but in most of the US you would have anything from a 3 to 7 degrees east. I am no scientist but I know what the maps said in different parts of the world and having to convert magnetic to true or magnetic to grid, these are the values we would have to use, found in the Maps Legend.

Nice of Lake Shore to donate that useful equipment to your channel. Good job, guys

happy new year mate !! keep it going !!

Was für eine Entwicklung! Mittlerweile einfach über eine halbe Millionen subs! Glückwunsch hast du verdient. Hab diesen Channel damals bei 10k abonniert

"Government shill! You and your spinning ball! Water always finds its level! RePeNt FoR yOuR sInS!" Thanks for the video. I love your channel.

Very good video, keep creatng valuable content ;) Also that litlle advertisment of that Tesla-meter was really pleasant to watch

Hi, I have a few questions. Firstly, I am not advocating for Flat Earth, Helicentric, Geocentric, Concave Earth, Convex Earth, Inner Earth, Infinte Plane, etc etc. I was watching a video, Professor Eric Laithwaite: Magnetic River 1975, and it spiked my interest in magnets. So if my questions seem basic or nonsensical it is because I know very little about them. 1. How is _"a compassed balanced in a way that makes it useful for horizontal navigation"_ ? 2. How does a compass and a dip circle differ, in relation to operation? 3. When you set up the F71 probe, did you also put a compass next to it to compare them for both for North? 4. _"It is believed that the molten iron and nickel in the outer part of the Earth's core is generating the magnetic field"_ This raises many questions, but I will ask just one. Are able to demonstrate or explain how this works, especially in relation to the Curie Temperature? 5. Or maybe two questions - if the molten core is sworling and moving and being affect by the "Coriolis effect" of the earths motion, why does it not produce smaller, more localised magentic fields instead of just one large one? As is demonstrated by the weather. 6. Isnt using a large magnet in the half globe model just a confirmation bias? 7. Did you try the compass on the "southern" half of the globe model? 8. Do you know someone in the Southern hemisphere that can do the same test? Or do you know of a video similar to this one that is performed in the South? Thanks in advance.

Interestingly, we here in the southern hemisphere cannot use a compass designed to be used in the northern hemisphere and vice versa. They are balanced to suit the hemisphere they are to be used in. If you do try to use one of the opposite hemisphere compasses (compii? ;) ) then the needle will hit the casing.

You follow in the footsteps of the old vikings and your famous countryman Oersted... The vikings are assumed to have sailed in the open seas using an early magnetic compass. Oersted put the science into the magnet business. Great visualizations! Here is a little memory from my childhood. I had a book, called something like “Young Inventors’ and Experimenters’ Book” that described how some boys showed each other their experiments and built items. Among those experiments was how to magnetize steel rods or needles. Then to verify that indeed it had become magnetized, the bigger rods could be hung from their center point to a thin sewing thread and it would turn to roughly North/South. Careful about the twist of the thread, though. But the smaller needles could be covered with a thin layer of butter and settled carefully on top of a full water barrel, where the surface tension kept it floating and it turned freely to N/S orientation. Guess what - I got one of my mother’s sewing needles and repeated the test. That served to teach me about surface tension in addition to the magnetism. And I can be proud that I also did NOT lose the needle.

First Video for me- very interesting, thanks. (Now Subscribed, to catch-up!).

I used to own a spherical compass my mom brought me from India, but it never worked properly because the airline security equipment ruined it :/ Edit: after watching the whole video, maybe my sphere magnet WASN'T broken and I just didn't realize it wouldn't point perfectly horizontally where I live. Huh

I have understood that magnetic north is actually in Northern Canada not the North pole which is true north and the magnetic north pole has been moving north and west of the north pole. The teslameter is such a cool device but you've misaligned the globe for magnetic north. I think you'd see better results on the globe if the globe had been adjusted for Magnetic north.

That was VERY interesting to watch, you got my sub! I know a few people I gotta share this to as well :)

This was cool to visually see on the teslameter. Thanks for posting this

Oh, those are the two magnets you permanently stuck together.😄 So I am genetically predisposed to live with a 65° to 70° magnetic pull on my body. Yet I was born and have lived in a place where the pull is more along the 45° angle. I will have strange ponderings over this now. Because living outside of my natural magnetic pull angle has made me a strange person.😉😄

Our siecne/math techer is back

this was such a great video. Very very well explained and I definitely learned something new! Great work!!!!

Thank you to the patrons who help you. What a wonderful science demonstration. Thanks

I learned something new today. Thank you!

That is also why marine compasses are gimballed and have large vertical freedom. No flat earthers around people who have seen someone sail off over the horizon when out of sight of land.

Keep up the great work. Your videos are both thought provoking and intellectually stimulating!

What a brillant demonstration, not only about the inclination of the earth magnetic field, but also of how a scientific intuition can become a subject for testing a method, in search for more accuracy.

8:55 best line never used by Rik & Ade in any of the Bottom live shows! (wish they had though!)

please can you repeat this experiment using a flat earth model map

Was leveling a pool table with friends help. They didn't believe me when i stated that rolling a glass marble on a piece of flat glass would be far more accurate than a carpenters level. After i got the marble and glass out they wondered why i spent so long cleaning it and checking for one without scratches, they didn't believe when i said a tiny scratch or speck of dust can prevent the marble from rolling. I explained that the amount of contact area between a round object and flat one is tangential and that a speck of dust is pretty big compared to that. Later i explained that flat glass is a modern invention and that old glass was never as flat and its amazing we as a species could create such flatness on a surface so hard to work with. That made me curious how it was produced and i later researched it. They never did believe me and all 3 of em went home thinking i was dumb and spouting nonsense all day... Post ended up being a paragraph lol, im still annoyed by this.

Now THAT was fascinating. Cool that you even thought of this experiment.

Did you figure out this yourself, wanted to re-produce it or was curious after some statement people had ... either way ... very well done ! Expect your video to pop up in many flat earth arguments :)

Do you want to experience true level?

Actually, in many ways, THIS is your coolest video.

This came up on my suggestion feed. Glad I watched, had no idea magnetic fields were actually measured like this. I like to learn and this was very interesting indeed.

I'm still wondering how molten metal can be magnetic, as you know the higher the temp in most metals the less magnetic it gets. The reason they are magnetic at all is the orientation of the grain structure in them is locked in a certain position. So if the magnetic field were really generated by flowing magma or a spinning core it would be unbelievably unstable and varying if it functioned at all.

Excellent video, have you seen the 3D compass on Grand Illusions?

One of the best education RU-vid videos I have even had the pleasure of watching. Great work!

This is the first video I watch from you. Your little comments are funny :)

Congratulations. You just discovered how pigeons and other birds navigate. The Sun gives longitude while the vertical magnetic field gives latitude. Inside their brains are round structures containing molecular sized magnetized iron particles that due to gravity sit at the bottom of these cavities. Just like the demo you used at the end where the compass points vertical at the equator and horizontal at the north pole, these iron particles shift position inside the cavity and their polarized location is processed by their brains to give them latitude.

At 5:36, you could have taken 90-180/pi*sin(180/498) and gotten 69.74 degrees.

Great video and very educational. Now I have a new bit of knowledge of earth's magnetic field.

Adding to the variation is that the magnetic north pole is not the same as the true north pole. The magnetic north pole is in northeastern Canada somewhere, though, apparently, it has been slowly shifting closer to true north over the last century.

interesting about the fall of a magnet, never thought of that.

So why ain't we able to to levitate by making a platform of a magnet pointing same direction as the earth's pole ... To create a separation from the earth or resistance... Hummm i wonder.... May be there is not such a thing of magnetic field ... Or if it is so it may not work exactly as we thing ... So that being said this experiment or anything similar to this wont tell us much ...

Wow - great video. I was just talking to my pre-teen about magnetic polarization and its role in proving the theory of continental drift. This video will be a great way to help him understand!

Great work to illustrate with such a simple explanation. Cheers.

Watch brainiac, if you want to know the gravity of the situation!

Can't wait to see the flat earthers make a working model of this! LOL!

You can actually do the same test with your smartphone. The highest you can get when the phone is level pointing north is around 22-23 μT, pointing it north but angled downward however this goes up to 50μT!

A _real_ Brainiac on RU-vid! Subbed.

Awesome video man. Im writing a book currently that uses this is a world power source. its "fiction" because im not an actual scientist. BUt i think i figured it out.. (so far only works on a small scale.)

Yes. Earth is rectangular and flat. Also, there is a hole in each corner and in the center of two longer sides. Earth is actually God's pool table. Compass arrow is pointing to the spot where the white ball is placed. QED.

this was amazing, thanks a lot for the video !

That's cool that your crudely made sphere test was so accurate.

nice

I could only wish that physicians, historians could start every sentence with worlds: as our today's best knowledge... Im sick of all those theories who are 100%right today and they are scrapped in next 10 years.

the tesla meter looks like a high end audio amp. And seems to be working really nice. Thanks for the interesting video!

Can you determine the depth of the magnet on your instruments by triangulation? I'm curious if it's 7.6 miles - the depth of the Kola bore hole - the point where they could drill no deeper. Let me know please.

It would fall upside down in the land down under

Someone sent you a $6000 Teslameter???? Damn!!!!! Nice giving person i guess.... Cool experiment.

3:10 Where did you film this at? what Country ?

Wow that was kool!! Thanks for shairing that!!

i dont understand this, earth is round, north pole is north, so unless u are within (~100km?) of true north it wont point down? whats the point? if u stand right in the center of the south pole it would point straight down and a level compass would spin? please explain whats the point of this video

The earth is clearly not flat peoved by this

Wonderful demonstration! Something I had not considered before, Thank you.

Thanks for doing this. It offers some interesting details when considering that the core rod of a GEET plasma reactor that is tuned in line with the Earth's horizontal field is tested vertically, it is found to be north upwards, no matter what end is up. Good stuff. Peace, B

I am the 50th viewer

Add this to the long list of ways to disprove flat earth.

"this is a mountable probe but I'm lazy and just eyeball it by hand"... I feel you bro ☝🏽

Very nice.... and thank you Lake Shore company!
