A copper wire with square cross section carries a conventionalcurrent I in the +y direction. There is a magnetic field B inthe -x direction. Draw a diagramillustrating the situation, to help you answer the followingquestions.
What is the directionof Eparallel, the electric field thatcauses the current to flow?>What is the direction of the drift velocity of the mobileelectrons?What is the direction of the magnetic force on the movingelectrons?What is the direction of Etransverse, theelectric field due to the Hall effect, inside the wire?If the mobile charges had been positive (holes) instead ofnegative, what would have been the direction of the magnetic forceon the moving positive charges?If the mobile charges had been positive instead of negative, whatwould have been the direction of the transverse electric field?
