Question

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


A
An e.m.f. is induced in the coil
loader
B
A current is induced in the coil
loader
C
Both e.m.f. and current is induced
loader
D
Neither e.m.f. nor current is induced
loader

Solution

The correct option is C Neither e.m.f. nor current is induced
 Given : A coil of metal wire is kept stationary in a non-uniform magnetic field.

Solution : 
Solution of this question is based on Lenz's Law
Lenz Law states that if there is a procces in which magnetic flux in a metalic object changes then there will be induced EMF and induced current which will create a magnetic field to oppose the change in magnetic flux. 
In this question coil of metal wire is stationary and there is non uniform magnetic field which is not changing with time. Hence ,there is n change in magnetic flux so no EMF or current will be induced.
