I am studying electricity and magnetism in physics right now, and I'm having trouble with the force from a magnetic field on a moving charge. I understand the right hand rule, but I do not understand how to determine which way the force acts on the charge. This particular problem sums up my confusion pretty well. The asterisk is an electron, moving the same way as the current in the wire. The B-field at the electron should be pointing out of the page, but how can I figure out which way the force is directed on the electron? *---> =====WIRE=====> Thanks for any advice!!!
