A conductor AB lies along the axis of a circular loop C of radius r. If the current in the conductor AB varies at the rate of x A/sec, then the induced emf in the coil C is



(1) µ 0 r x 2                 (2) 1 4 π x r                     (3) µ 0 π x r 2                  (4) Zero

Induced emf in the coil would be zero since emf is induced along the coil.

zero because emf is induced by varying magnetic field not varying current

Induced emf is zero as there is no change in flux

Mag. Field lines on the circular loop due to the wire are tangential. Therefore, flux = BAcos90 =0. Hence, induced emf is zero. Hope it helps...... 😃
