Question

The current flowing in two coaxial coils is in the same direction. On increasing the distance between the two, the electric current will-

• A. Increase
• B. Decrease
• C. Remain unchanged
• D. Initially increases and decreases.

Answer 1

The correct option is A Increase

As increasing the distance between the two coils, flux linked with the coil decreases. according to Lenz's law the decrease in the flux must be opposed. Thus, current in the coil increase.
