A square, 55-turn coil 10.0 cm on a side with a resistance of 0.820 ΩΩ is placed between the poles of a large electromagnet. The electromagnet produces a constant, uniform magnetic field of 0.600 T directed into the page. As suggested by the figure below the field drops sharply to zero at the edges of the magnet. The coil moves to the right at a constant velocity of 2.00 cm/s.

1) What is the current through the wire coil before the coil reaches the edge of the field?

2) What is the current through the wire coil while the coil is leaving the field?

3) What is the current through the wire coil after the coil leaves the field?

4) What is the total charge that flows past a given point in the coil as it leaves the field?
