3a) An electron is moving due north when it enters a magnetic field directed downwards toward the ground. What is the direction of the magnetic force on the electron?

b) The magnetic field strength 0.5 m away from a long straight wire is 7.2 x 10^-7 T. Calculate the current in the wire.

c) A single-turn wire loop of radius 5 cm rests flat on a table which is perpendicular to a magnetic field of strength 3.4 T. The field strength is turned down and it takes 0.08 seconds to reach 1.2 T. Calculate the magnitude of the emf induced in the loop.

An electron is moving north; what direction should a magnetic field be oriented, so the magnetic...

An electron is moving north; what direction should a magnetic field be oriented, so the magnetic force on the electron just balances the gravitational force? A square loop is in the x-y plane, with its top and bottom parallel with the x-axis, and its sides parallel with the y-axis. It carries a clockwise current when viewed from the positive z-axis. There is a constant magnetic field pointed in the x-axis direction. What are then directions of the magnetic forces on the four...
