Shrinking Loop.
A circular loop of flexible iron wire has an initial
circumference of 164 cm , but its circumference is
decreasing at a constant rate of 13.0 cm/s due to a
tangential pull on the wire. The loop is in a constant uniform
magnetic field of magnitude 0.500 T , which is oriented
perpendicular to the plane of the loop. Assume that you are facing
the loop and that the magnetic field points into the loop.
Find the magnitude of the emf induced in the loop after
exactly time 9.00 s has passed since the circumference of
the loop started to decrease.
Express your answer numerically in volts to three significant
figures.
