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

A

the current in each will decrease

B

the current in each will decrease

C

the current in each will remain the same

D

the current in one will increase and in other will decrease

Text Solution

Verified by Experts

The correct Answer is:
A

Source flux `phi_(1)` increases so induce flux will oppose the source flux that's why it will produce.
Current in opposite direction to main current. So current in each will decrease
