A wire is bent to form the double loop shown in figure. There is a uniform magnetic field directed into the plane of the loop. If the magnitude of this field is decreasing, current will flow from:

A

A to B and C to D

B

B to A and D to C

C

A to B and D to C

D

B to A and C to D

Text Solution

Verified by Experts
