A small, closely wound coil has N turns, area A, and resistance R. The coil is initially in a uniform magnetic field that has magnitude B and a direction perpendicular to the plane of the loop. The coil is then rapidly pulled out of the field so that the flux through the coil is reduced to zero in time At.

A small, closely wound coil has N turns, area A,
and resistance R. The coil is initially in a uniform
magnetic field that has magnitude B and a
direction perpendicular to the plane of the loop. The
coil is then rapidly pulled out of the field so that the
flux through the coil is reduced to zero in time At.
Part A
What are the magnitude of the average emf Ey and average current Iny induced in the coil?
Express your answer in terms of the variables N, A, R, B, and At.
