A circular coil of 238 winds of wire (radius =6.3 cm, resistance =6.3Ω ) is placed in a uniform magnetic field that is perpendicular to the plane of the loop. The magnitude of the field changes with time according to B=20sin(1t)mT, where t is measured in seconds. Determine the magnitude of the current induced in the loop at t= 1
