Thanks, my teacher could absolutely not explain this in a way that made sense

[nicolascruzmedina]

best video I have seen so far about Hall Effect. Thank you very much.

This is fantastic! I especially like the way you describe the substitutions in the formulae. I don't have to pause the video to search out why the variables in the formula suddenly changed. Allowing me to stay focused on the subject. No one else does this! Thank you.

Lovely explanation, much appreciated. Great series.

[Pearl-kusz]

I don't usually comment, but the explanation in this video deserves on oscar!

[linabouaamri]

Thanks for this amazing video I thought that I would never understand it

[aronkloepping]

what a great explanation. Thank you very much!!

[emmapasqule]

This is brilliant. Thank you SO much. You explain things so clearly and the graphics are super helpful. Thank you, this is so appreciated.

Thank you very much for this brilliant video.

In your video about Maxwell equations you said that only MOVING charges create magnetic field.

So, in permanent magnet should be permanent current, that creates this magnetic field???

3:40 How can we siubstitute v by (L/t) even though that the electrons do not have an uniform motion?

[leonardosoto]

What if our charge carriers are positive charges?

[angelaguilar]

I'm confused about the direction of the Lorentz force. If my left middle finger goes from left to right and my left index finger does toward the screen, my thumb points downward, not upward. The open right hand rule backs this up: if my thumb (current) goes from left to right and my fingers (magnetic field) go toward the screen, my palm (force) also points downward.

[dadyex]

is F= Qv x B since it is cross product why is the left hand rule used and not right hand

[casperyu]

Current is not equal to electrons current?

[bhavanishankar]

Ammeter in Parallel to measure current, how can that be possible, we use Voltmeter in Parallel and Ammeter in series to measure Voltage and Current respectively

[wubwub]

i got lost when you brought in the small n

[lambda]

man used left hand rule instead of right 💀

Actually not a good explanation without context and reference to common applications. This is the abiding 'disease' of so-called 'pure' mathematics and its practitioners and explains why so few invent anything. Only when they cross over to the applied field does this occur.
Edwin Hall, like his near contemporary Ernest Rutherford, always sought actual uses for phenomena they discovered and frequently made their discoveries in the process of working with things on benches and not chalk on blackboards.

How can you know the magnitude of magneticfield
