Question

(ii)
If a coil of metal wire is kept stationary in a uniform
magnetic field, then
(a) an e.m.f. is induced in the coil
(b) a current is induced in the coil
(c) neither e.m.f. nor current is induced
(d) both current and e.m.f. are induced,​

Answer 1

If a coil of metal wire is kept stationary in a uniform  magnetic field, then:

(c) neither e.m.f. nor current is induced.

- Since the magnetic field is uniform and there is no relative motion between it and the coil, hence no emf will be induced in the coil.

- Since there is no induced emf in the coil, hence no current will be induced it.

Answer 2

Option C is correct

neither e.m.f. nor current is induced

Explanation:

• E.m.f produced when there is a movement in the coil,  
• As there is no movement, so there will be no electromagnetic induction in there
• As the coil is stationary, there is no variation in the magnetic flux, so no current or e.m.f is produced
