Question

Two identical coaxial circular loops carry a current I each
circulating in the same direction If the loops approach each other, you will observe that

• A. the current in each increases,
• B. the current in each decreases,
• C. the current in each remains the same,
• D. the current in one increases whereas that in the other
  decreases

Answer 1

The correct option is B the current in each decreases,

Since, both loops approach each other and carry current in same direction, the magnetic flux linked with coil will increase

Hence, current in both loops will decrease in order to diminish the effect of increasing flux.

Hence, answer is option-(B).
