A rectangular conducting loop is being pulled at constant speed v=4.00 m/s from a region of uniform magnetic field by a constant external force F. The dimentions of the loop are w=.3 m, l=.9 m, and has a resistance of R=5 ohms. In the region where the magnetic field is nonzero, it is directed out of the page and has magnitude of 3.00 T.
External force is to the right, magnetic field is pointing out of the page, and velocity is to the right.
a) What are the magnitude and direction of the current induced in the loop while the loop is being pulled out of the magnetic field region, but is partially in and partially out of the field?
answer is 0.72 Amps counter-clockwise.
b) What is the rate at which the external force F is doing work on the loop?
answer is 2.59 W.
PLEASE show me how to arrive at these answers!
