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

Options

  1. Aincrease in both
  2. Bdecrease in both
  3. Cremain unaltered
  4. Dincreases in one and decreases in the second

Correct answer

A. increase in both

Step-by-step solution

On moving the circular loops further apart, flux linked with loops will be reduced. Therefore, according to Lenz's law, current will increase in both circular loops to increase the linked flux.
