Q133 / 200 · NEET 2022 (Phase 1) · Physics
A big circular coil of turns and average radius is rotating about its horizontal diameter at . If the vertical component of earth's magnetic field at that place is and electrical resistance of the coil is , then the maximum induced current in the coil will be:
- A
- Correct answerB
- C
- D
Solution
The magnetic flux is given by,
. Therefore, induced EMF,
For maximum current
Hence, the correct answer is option: 'B'.
