The coil and magnet are moved in the same direction with same speed (V). The induced e.m.f. is (a) zero. (b) proportional to V. (c) proportional to V⁻¹. (d) finite but does not depend on V.

Answer: (a). Induced emf needs a change in flux through the coil, which needs relative motion between coil and magnet. Both move in the same direction with the same speed V, so their separation stays constant. Flux is constant, so e = 0. So the answer is (a) zero.

The coil and magnet are moved in the same direction with same speed (V). The induced e.m.f. is

Show answer and solution

Answer: (a)

Induced emf needs a change in flux through the coil, which needs relative motion between coil and magnet.
Both move in the same direction with the same speed $V$ , so their separation stays constant.
Flux is constant, so $e = 0$ . So the answer is (a) zero.
