Shows a coil placed in a decreasing magnetic field applied perpendicular to the plane of the coil. The magnetic field is decreasing at a rate of `10 T s^(-1)`. Find out current in magnitude and direction of current.

Text Solution

Verified by Experts

`phi = BA`
`emf = A(dB)/(dt) = 2 xx 10 = 20 V`
`:.` `I = 20//5 = 4 A`. From lenz's law, direction of current will be anticlockwisw.
