Electronics 101: The Hall Effect explained 

The magnetic field, the current created by the voltage applied to the Hall affect device and the force acting on the electrons should be all orthogonal to each other. So on your white board the north pole of the magnet should be behind the white board and the south pole in front. Fleming's Left Hand Rule (for motors) gives these directions (it uses conventional current flow, even though that was subsequently shown to be the opposite to reality) would have the positive of the applied voltage at the bottom of the device illustrated with the negative on the top (if the negative of the Hall voltage is to appear on the right of the of a Hall affect device as illustrated).

Such an enthusiastic conductor. We love you for all the conducting you do.

This is an incredible explanation of a microelectronics concept that I've had difficulty grasping in the past. Thank you for taking the time to make it clear. Cheers!

Love these types of videos. Thanks Bruce!

Fantastic video, I looked everywhere for good explanation and I couldn't find a better one! Thank you for uploading.

Love these types of vids... Always fun to learn how everything works.

This kind of teaching we need in our school system. I really believe when someone explain the things very well, he really understood the subject... I was trying to understand the principle of our turbine meter which has a pickup coil and a rotor. And I'm not sure how the pulses are generated. Now it's very clear to me and i know how to troubleshoot the equipment. Thanks sir.

You sir, are a wonderful teacher. I can tell that you love knowledge and that you enjoy sharing it with others. You've made this concept very easy for me to understand. Thank you so much, God bless!

Good explanation of a "mysterious" electronics term. I LOVE this sort of video. Many Thanks Bruce.

Thanks for that video, this is certainly the best explanation I've seen so far.

It would be cool if you "electrically " took us from the radio transmitter we hold all the way through the prop spinning on an electric plane.... and everything in between. These are great and we learn so much!!!!! Thanks Bruce!

Thanks for the great video. This is the best explanation I've see so far. Looking forward to more of these theory videos.

Thanks bruce...helped me understand my hall effect distributor, on my truck

Hello Bruce! Great video again, love the whiteboard! Would love to watch a whiteboard video about optimization of power combo, from props to batteries, going through motors and ESC's, taking into account the weight or flying characteristics desired. I know it's way too much for your small whiteboard and your almost finished markers, but you have managed yourself to explain so many things that I would think this is not a big task for you! Thank you for your passion!

Excellent explanation. Thank you so much. You’ve really made this very clear and are unique in your ability to make the complex understandable!

i love these electrical theory videos Bruce! cheers!

Your whiteboard videos are my favorite. Keep em coming Bruce! :)

Learned something today! Thanks for the video!

great one Bruce......I had a go at explaining hall and its benefits in one of my videos but not a patch on your explanation.....

Now this explained the hall effect its been since about 1964 since I studied electronics 🤤 I watched some other guy do an art lesson that left me more confused than when I started thank you for the simple well done explanation

I love your disclaimers at the end of technical vids. I suppose they cut down on the geeky nit-picking a little but probably not enough. ;)

Thanks Bruce, makes it simple to understand.

I've never seen the letter "S" written bottom to top. Great video: simple explanation of a complex subject.

Great work! More of this, please!

Thank you Bruce. You are a excellent physics teacher!

You are incredible at teaching and explaining, I love your sense of humor!

Thankyou for this vid. Very informative. Keep up the great content.

Simplifying stuff is a skill , RESPECT.

Nice quick video. I believe you have the direction of the magnet (magnetic field) mixed up. In the orientation you show the magnetic field is parallel with the movement of the electrons. The cross product between velocity and magnetic field would be zero. The magnetic field would have to be either into or out of the board.

This is a great help! Thank you RCMR:)

Thank you so much for your help! A great easy to understand explanation!

Awesome! Explained simply. Appreciate you!

I always like watching your videos. Thank you.

As a car mechanic this has helped me understand more how the sensors work in cars Crankshaft / camshaft / distributors mostly use hall sensors. Thank you

Great video. Great presentation. Thanks Bruce

I thoroughly enjoy your videos. thanks

you explain it really well!

Yes please, an explanation of how those solid state gyros work. Black magic I guess. Keep up the great work Bruce.

Great explanation - thank you

Very good video. Clear and instructive. Thanks much.

That was a bloody wonderful explanation, well done!

So now I know what the hall effect is. Great video mate.

As usual really interesting. Thanks!

I learned something again. Thanks.

Very clear, thank you. Please discuss the different types of Hall sensors, especially the quantum hall sensor. That sounds interesting.

Thanks for your efforts!

A very good explanation. Thank you.

Wouldn't the electrons be redirected in the direction into the whiteboard? Because F=q(E+v x B) where there is no external electric field, but the velocity is up, and the magnetic field is to the left, and the electric charge is negative. So by cross product I expect the applied force would point into the page.

always love when the white board comes out. i know im going to learn something good :)

this was amazing. thank you

Tq for ur great explanation Mr. Bruce.

Love your videos. Simple to understand. Gets me there quickly to get a GRASP on the subject. Looking at the thumbs down on a few and wondering why there are as many as there is. Then I realize they are the poindexters that go ( in a nasally voice) ," you said pie is 3.14. Nuh uh, your wrong it's 3.1415." We that watch your videos are laymen and don't have time to watch a 10hr video on the truest form of the subject and probably wouldn't even grasp it anyways. These videos are to get us in the ballpark on a subject and get the AHHHH I kinda understand now. Love your vids Bruce.

Very useful information thanks to you I have never had heard about it before

Congratulations Bruce!!!

great video, i look forward to the next whiteboard

Learning the Hall Effect from a bloke in a flannel. Love it :)

That helps a lot. Thank you!

Thank you, Bruce you explain things so well keep up the whiteboard we love it :D cool you talk about vintage ESC pod still have a few Tamiya vintage rc car ESC controlled by a servo and still work after 30 years

Nice one Bruce..Thanks.

Good explanation sir thanks for sharing

Thanx. That was informative and fun. Well done.

Very interesting! Thank you

I did learn something today. Thanks.

Thank you for this information

Thank you Bruce

i think you did a great job. Thanks

Thanks, you explain very nice I understand immediately

Great great you make it a joy to learn

Very interesting clear and well explained thanks

Sorry but I've got to say this: always you get some one trying to boast how good they are ( electrons don't do that), COOL it you guys, Bruce was using the simplest explanations as to what hall effect is, so that everyone can understand. He's not doing a course in advanced electronics.

Another great video.

Thanks Bruce!

Nicely explained sir.

Brilliant teacher, thanks very much 😊

Wow. Residual voltage defined.I love it.

Excellent teaching about sensor sir ,thank you sir.

Also, some ESC for brushless motors (most of the sensored ones) use Hall effect sensors as a feedback, to control timing.

Do you ever get a Hall effect when you walk along a corridor?

Awesome video mate! Finally someone explained it really well. Would you please do a video on TWO wire Hall Effect?

Thank you. Nice and simple

Hey retro! I like your style! Nice work!

very educative. thank you regards

Cheers Bruce , nice one

Thank You!

The explanation was superb. Especially the bit with the op amp . . . you might include a Schmidt trigger in your next one.

awsome

Actually they are pushed to the side by the magnet. Which side depends on the pole of the magnet that is closest to the sensor. For the shown deflection the magnet would have come from the direction of the pen on the board, not in the plane of the board. Apart from that a very good explanation.

I was told the accent is learned by a very young child. Lip movements are recorded. Very good explanation.

Great video Mr. White!!!!

Thanks mate fascinating as always , ..

Thank you for this!

I’m glad to see Whitey Bulger decided to make a career change . Also, excellent explanation , thanks !

You are the teacher ive been missing my whole life idk how kany videos ive randomly watched but you hleped me understand so easily ive been wondering lately what effect a magnet would have on current, thank you !!!!!! Is there any way i can get specific answers on certain questions not normally asked?

Very interesting RESPECT man

Great stuff 😊

Very interested. Cheers Bruce.

Bloody brilliant. Thanks!

Thanks, God bless,

Good video!

How can you use the hall effect as a switch using the electrostatic energy from a finger for example? e.g. touch lamps
