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

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.
