When two coaxial coils having same current in same direction are brought to each other. then the value of current in both the coils

Options

  1. AIncreases
  2. BDecreases
  3. CRemains same
  4. DIncreases in one coil and decreases in other coil

Correct answer

B. Decreases

Step-by-step solution

When two coaxial coils having same current in same direction are brought to each other, then flux linkage to each other increases. So, by Lenz's law, the current in both coils decreases in order to oppose increase in flux linkage between them.
