A coil consisting of 200 turns of wire has its ends connected to a circuit such that the total resistance of the coil and the circuit is 2.0 ohm. There is no source of e.m.f. in the circuit. Each turn of the coil is a square of side 18 cm, and a uniform magnetic field directed perpendicular to the plane of the coil is turned on. If the field changes linearly from 0 to 0.5 T in 0.8 s, what is the magnitude of the current in the coil while the field is changing?
