Two identical coils, each carrying the same current l in the clockwise direction as shown in figure, are moved towards each other with the same speed, then, the current

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 the induced current will induces in the direction opposite to original current according to Lenz law and hence current in both P and Q decreases.
