Two similar circular loops carry equal currents in the same direction . On moving the coils further apart , the electric current will

A

remain unaltered

B

increases in one and decreases in the second

C

increase in both

D

decrease in both

Text Solution

Verified by Experts

The correct Answer is:
C
Two circular loops carrying current in the same direction will attract each other . If other . If they are now separated , induced currents will try to keep status quo, by increasing the current in both the coils.
