Question

Two coils of wire A and B are placed mutually perpendicular as shown. When current is changed in any one coil,

• A. no current will be induced in another coil.
• B. magnetic field will be perpendicular to plane of another coil.
• C. magnetic flux linked with another coil is maximum.
• D. current induced in another coil is maximum.

Hint:

For electromagnetic induction to occur, the magnetic flux linked with the coil must change. In perpendicular orientations, no flux linkage occurs to induce current.

Answer 1

The Correct Option is A

Step 1: Understanding electromagnetic induction.
For electromagnetic induction to occur, the magnetic flux through the second coil must change. In this case, the coils are placed mutually perpendicular to each other, so when current in one coil changes, the flux through the second coil does not change. Therefore, no current will be induced in the second coil.
Step 2: Conclusion.
Thus, no current will be induced in another coil, corresponding to option (A).
