If the inductance of a magnetic circuit is 0.4H. The energy stored in the coil when the instantaneous current at t=1sec is 1A .

 

A coil consists of 200 turns of wire. Each turn 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 0.50 T in 0.80 s, what is the magnitude of the induced emf in the coil while the field is changing? What is the magnitude of the induced current if the resistance of the coil and the circuit is 2.0 ??
