An N-turn square coil with side l and resistance R is
pulled to the right at constant speed v in the positive x - direction
in the presence of a uniform magnetic field B acting perpendicular
to the coil, as shown in Figure P20.66. At t = 0, the right side of the coil is at the edge of the field. After a time t
has elapsed, the entire coil is in the region where B =0. In
terms of the quantities N, B, l, v, and R, find symbolic expressions
for (a) the magnitude of the induced emf in the loop
during the time interval t, (b) the magnitude of the induced
current in the coil, (c) the power delivered to the coil, and
(d) the force required to remove the coil from the field. (e)
What is the direction of the induced current in the loop? (f )
What is the direction of the magnetic force on the loop while
it is being pulled out of the field?
