Two circular, similar, coaxial loops carry equal currents in the same direction. If the loops are brought nearer, what will happen?

A

P increases while in Q decreases

B

Q increases while in P decreases

C

both P and Q increases

D

both P and Q decreases

Text Solution

Verified by Experts

The correct Answer is:
D
When the coils P and Q are brought nearer, the magnetic flux linked with each coil will increase and so the induced current will try to decrease the flux and hence current in both P and Q decreases
