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.

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???

Nope, the spin of the electrons creates the permanent magnet

@angelaguilar497 2 ай бұрын

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.

@benatkinson3160 2 ай бұрын

index finger = magnetic field, thumb = force, middle finger = current (direction of positive charge flow). each of those three quantities are vectors whose direction is the direction your finger points in :) if the question talks about negative charge moving left then you must make sure to point your middle finger to the right

@dadyex4210 Жыл бұрын

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

@ikitashou1490 Жыл бұрын

@@loainakhly how ?, it's a negative charge so the magnetic force is reversed. just put your fingers into the screen with a thumb to the left of your right hand. The applying force opposes your palm direction

@MrBej Жыл бұрын

wait I don't get it, shouldn't we be using the LHR to find the motor effect on the electron placed in a B field?

@iamnotalive1155 Жыл бұрын

No you use the LHR for the force on a positive charge, and use right for electron but honestly just use the LHR for all of them and when encounter an ele just pretend the current is going the opposite directing while assuming it acts like a proton

@@iamnotalive1155 yeah exactly, that's what I thought. Thanks for clearing it up. I've been told to use the RHR only when finding the direction of the induced current.

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.
