A circular loop of flexible iron wire has an initialcircumference of 165.0cm, but its circumference is decreasing at aconstant rate of 12.0cm/s due to a tangential pull on the wire. Theloop is in a constant, uniform magnetic field orientedperpendicular to the plane of the loop of magnitude 0.500T.
A. Find the emf induced in the loop, at the instantwhen 9.00s have passed. Express your answer in volts.
B. Find the direction of the induced current in the loop,as viewed looking along the direction of the magnetic field insidethe loop.
