A coil consists of 20 turns of wire. Each turn is a square of side d = 1m, and a uniform magnetic field directed perpendicular to the plane of the coil is turned on. If the field changes linearly from (0 - 5 T) in (10 s), what is the magnitude of the induced emf in the coil while the field is changing?
