Question

In the case of a current carrying coil, the induced EMF is maximum when the coil's plane is:

• A. Parallel to the magnetic field
• B. Perpendicular to the magnetic field
• C. At an angle of 45°
• D. At an angle of 90°

Hint:

To achieve maximum induced EMF, position the coil at an angle of 90° to the magnetic field.

Answer 1

The Correct Option is C

Step 1: Lenz’s Law and Faraday’s Law of Induction. The induced EMF is maximum when the change in magnetic flux is greatest. This happens when the plane of the coil is perpendicular to the magnetic field.
Step 2: Conclusion. Thus, the induced EMF is maximum when the coil's plane is at 45° to the magnetic field.
