These magnets are not solid metal - they are made of a crystalline structure with an outer metal coating. So they are rather fragile and will chip or even shatter rather easily. Since they are also quite expensive I tend to do everything with care. This is also an instructional video so fast pace would ruin the purpose :) Care is even more important with larger magnets where you really have to think one step ahead or you could loose a finger or two if something goes wrong! Thanks for watching!
I've seen quite a few of your videos on Rare Earth Magnets and I have to say I really like your presentation style, editing capability, and your techniques for handling rare earth magnets. I just ordered a bunch of small ones to use for experimentation and I feel much better working with them thanks to your videos.
@Inv8erZlM : Thank you and to all commenters on this video! I use Pinnacle Studio HD version 14 but I will upgrade to Avid Studio when I can afford it. Pinnacle Studio crashed at least 100 times during the editing of this video. Editing 1080p video is very demanding for the soft- and hardware...
Yes - this summer when I have holiday and therefore time to make videos. I will make a video of my collection and do some comparisons of the power of my larger ones. I have had several requests for this. Right now I'm concentrating on earning money at my job though :)
Neodymium magnets are generally very difficult to demagnetize. Other types of magnets (especially Alnico) can be demagnetized just by impact. Neodymium magnets are not supposed to be demagnetized by a hit but they will easily chip or even shatter so don't let them smash together :)
I remember as a kid trying to find a way to levitate stuff with magnets, but couldn't figure it out, looks like he has figured it out :-) I did the magnet checker pattern as a kid, but did not know that could work.
Yes, there are neodymium magnets in HDD. They are quite small in newer HDD and can be a pain to get out and of the mounting brackets though. And they are highly specialized with 4 poles instead of 2.
Sorry but no. I have no idea how to pull that off. Forcing 8 neo magnets with the poles facing the same way together in a steel ring sounds like a nightmare to me... I'm not saying it's impossible though. But the risks of chipping and scratching the magnets are high and I can't think of a way to eliminate the risks.
@IroniMan100 : Thank you! Bummer about the ban of magnets :( You can do it with small round magnets but it's way more tricky and therefore risky. Put nine magnets in a row with alternating poles and then 'fold' the row into a 3 x 3 square. But I'll admit that round magnets are hard to control. You have given me challenge for a new video :)
Thanks! When I started collecting these neo magnets I was surprised by how little information and videos there were about how to handle them in different situations. That was basically what kick-started my channel here on RU-vid :) Much more to come on how to handle neodymium magnets. Thanks for watching :)
I bought it from an Australian seller on eBay and pyrolytic graphite is always expensive. €5 for a 16x16x0.5 mm piece is reasonable and a perfect size for magnetic levitation and you don't have to cut a piece from a larger chunk as I had (it's not that easy).
@ldog1991 :You could get much higher magnetic forces with electromagnets but you need alternating poles over a surface to get stable levitation. In practice I think it would be quite a challenge to do this with electromagnets - I have no experience with electromagnets...
@ldog1991 : Yes - but grade N52 are as powerful as permanent magnets gets... With thicker magnets it should levitate higher but it would be minimal - probably barely noticeable.
I am going to try make the setup but i have some question: What is the minimum size for the magnets, for it to work and which size do you recommend, how many magnets should i use, how do i find the right size of the pyrolytic carbon, and is there difference between disc and rektangular pyrolytic carbon plates. Great and very interesting videos, and keep up the good work.
+TheKradok Hi, it's really not that difficult to get to work. Just make sure the pyrolytic carbon is as thin as possible and smaller than the area of the magnets put together. 4 magnets are enough as long as the carbon piece is smaller. The shape of the pyrolytic carbon doesn't matter.
Now you should take 27, and make a 3x3x3 cube with all of them. That would be awesome! Also, I think it would be interesting to see your larger magnets interact with ferrofluids, and magnetic silly putty.
Oh yes, that would be an interesting project. The Rubik's Cube from Hell x) I definitely need to make a video about ferrofluid and the magnetic silly putty...
The magnets do affect the diamagnetic water but not enough for it to be visible just by placing a drop of water on top of them. I show the diamagnetism of water (ice) in this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-I2pmV_jjC7c.html
0.5 mm is quite thin and will be very difficult to split further - do you mean 0.5 cm? If so search for the video 'Cutting pyrolytic carbon'. That's what I followed for splitting it thinner. Hint: use a very sharp knife or it will be too difficult. Good luck with your new toys :)
Thanks :) Depends on where you live. eBay is always a good source but there are also dedicated webshops like supermagnete'de (Europe) and magnet4less'com (US).
One question - what's the point of having both horizontal and vertical magnet "stacker" - isn't horizontal easier and really the only one you need - you can always lay them down or straighten them if you want, right??
+Corwin Maximus Yes, the final, vertical stacking for storage shown from 5:22 could also be performed horizontally. But for added security the final wedge has 'lips' on the sides making it impossible for the magnets to fly around the edges. With another wedge it could be done horizontally.
What WOULD happen if you just let two magnets smash against each other without the assembly and disassembly tools? Have you already made a video showing this? I see potential for some cool slow-mo! Keep up the great work!
They accelerate violently at each other and will chip/shatter since they're fragile. Once broken, they will corrode very fast. There are already videos showing how they break, send shrapnel flying around - and even sparks since the material inside is pyrophoric in small particles :) I haven't made a video where they are destroyed though. Love 'em too much and they're expensive... Thanks for watching!
The pyrolytic graphite will hover higher the stronger the magnets are - but the difference will be very small and almost unnoticeable. We are talking millimeters at best. And yes, freezing neodymium magnets will make them a little stronger.
whats up with the random jumping and twitching after it seems to have locked in place in the air? do you have any video to make an item levitate in the air with an open top so only magnets in the bottom?
+iblis89 I simply blow on the graphite to make the movements - looks much more interesting than a static setup on video ;) This video is currently the only one I have with something floating freely on top of magnets with nothing above it.
Thanks for uploading, I have a question for you. I plan on purchasing 8 neodymium arc segment magnets which are meant to form an complete circle by alternating those with the N pole facing out and those with the S facing out. The circle formed has an inner diameter of 2" and an outer diameter of 2 1/4". I plan to force 8 magnets with the same poles into a steel ring with a I.D. of 2 1/4" to create a kind of radially oriented ring magnet. Do you know of a good way to go about this?
can u please give me a link from where i will be able to get 1 mm thick block shape ferrite magnets? i dont want neodymium magnets for my project... even the n30 grade is also too powerful for my project
I don't know where you live. If you live in Europe supermagnete.com has a 20x20x3 mm ferrite block magnet as the thinnest. A 1 mm ferrite magnet is really thin so may be hard to find. Have you tried eBay?
Could you Please help me? I would like to buy some bigger magnets for the Brushless motor project that i am working on. But the magnets i find here are really really expensive. I live in Denmark, and i would like to buy some cheaper stronger magnets. Do you have any idea's ? Thank you
bridgendesar Good question. I don't really know since these magnets are very hard to push together with the poles facing the same way. The graphite however doesn't really care if it's a south or north-pole it's facing - it will always be repelled by the magnetic field. So I guess the graphite would still float above the array.
bridgendesar When you put two magnets together side by side with the same poles pointing the same way you are putting a north pole against a north pole and they repel each other. But I understand why you are wondering because if you cut a large magnet in half, wouldn't you be left with two magnets sitting side by side with the north poles facing the same way? No, one of them would violently turn around. This indicates that magnets are under internal stress. I have heard of people trying to order a custom, very large neodymium magnet where the manufacturer refused to make it because the magnet would likely tear itself apart from internal stresses.
No One Thanks :) They try to shield the box that large neodymium magnets are delivered in: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1zO9nWgI_LY.html
@brainiac75 And if you use electromagnets? Also, would you care to try to make a "box" of magnets and make it levitate inside it? Though, with such short distance between the magnets and graphite, i think it won't be possible.
thanks for answering my question! :) if you may i have another one. what if you put a magnet on top of the checker board one? will it repel or attract the magnet?
Rowmhar Lao The magnet would be attracted to the other magnets and find one of the opposite poles. It would be quite risky since there would be a violent impact and all of the magnets could realign with high force (even chipping or shattering some of the magnets).
Almost all of mine are bought on eBay. For US I usually recommend magnet4less'com since they seem to have fair prices compared to e.g. K&J Magnetics. But I live in Europe and have no experience with the US magnet market myself.
Nice video! Im not really allowed to own magnets that strong where I live, but I managed to get a few magnets. But they arent squared, theyre round. :(
When I was 10 I had the two smaller disc shaped magnets and had them pinching my nose and I flipped the polarity of one and they both flipped into my nose and were pressing in-between the cartilage of my nose. not fun but I did get them out and learned a lesson with these powerful magnets.
I would also like some cheap magnets with a lot of power but that is not possible on todays market. The strongest permanent magnets contains neodymium or samarium which are expensive rare earth metals (even though they are not really that rare). For 'cheap' neodymium magnets search the German version of eBay (some will ship to Denmark) or go to supermagnete.de. For really large magnets the only source I know of is magnetportal.de.
This can be a simplified explanation of how some modern high speed trains work. The train hovers over a magnetic field and is pushed by electric/magnetic field. Last time I checked, the concept was still under development.
I bought some magnets for some personal projects... and yes, you wouldn't think ones the size of half of your thumb could draw blood like it did xD (they came attached and was trying to separate by hand. it did not work)
Yes, a nightmare is what I'm expecting. I think if I can pull it off it may have some potential. I think I'll leave the steel pipe a little long, cut 8 spaced notches into each end then glue a magnets and then fold the ends of the pipe over it to clamp it in place. I'll do this one magnet at a time until it's done. Makes sense in theory anyway. Thanks for the response.
I wish I could one of that magnet cube I really want to have 2 of that but I'm broke I can buy it if it's important but magnet is my own interest I really want one of those
I know how old this video is, but... goddamn, every time you work with magnets like that, even though I know you're _extremely_ careful and you _really_ know what you're doing, I just can't help but cringe _massively!!!_
+TAVOR VICEROY VALDOR Hehe, the lifting force is really low so the model train should be made of aerogel or even aerographite/graphene aerogel. That would be very cool though. I wish someone would give me access to it :)
The magnets would smash into each other, possibly chipping them. Fingers can also be caught in the magnets which could cut them or in severe cases break the bone.
I used a bunch of old magnets and got a model train I made to levitate 1.25 inches and the model weighs 200 grams, I'm saving money for editing software so I can make a video
Mostly for comfort. These magnets are strong enough to give a lot of pinches when handling them. It's better when they nibble from my gloves than my skin ;) Also the magnets are nickel coated. I handle them a lot and don't want to develop a nickel allergy.
you dont need this. you could make it work with cheap magnets. just set one magnet to its north pole. another magnet would stick to its south pole. but if you force them to stick on the north pole. one would run away from a magnet
GamerNot Foundroblox you’re just describing repelling not exactly the same as levitation using a weak diamagnetic. Those levitation kits on Ebay have electromagnetic Alternating poles and fixed magnets to keep the item in place or at least centralised.
+Screaming CypherD Klonez (WAS NEVER HERE) :〈 Hehe, it would be insane to try to twist a cube with 3x3x3 of these magnets. The magnets would fly apart and rearrange and likely shatter. But it could be a fun challenge just putting the cube together. Maybe I'll give it a try in a future video.
