Question

A rectangular coil of 20 turns and area of cross-section 25 cm2 has a resistance of 10 ohm. If a magnetic field which is perpendicular to the plane of the coil changes at a rate of 1000 tesla per sec, the current in the coil is :

Moderate
Solution

induced emf = 50 V

The current in the coil= 5A
