Question

A copper wire with square cross section carries a conventional current I in the -z drection. There is a magnetic fireld B in the ty direction. Draw a diagram fustrating the stuatbon, to help you anower the following questions. What is the direction of Eparalel, the electric field that causes the current to flow? What is the direction of the drift velocity of the mobile electrons? what is the direction of the magnetic force on the moving·lectors? What is the direction of the electric fiold due to the Hall effect, inside the wire? +z If the mobile charges had been positive (holes) instead of negative, what would have been the drection of the magnetic force on the moving postive charges? -Select- If the mobile charges had been positive instead of negative, what would have been the direction of the transverse electric field?
