NEET 2022 Physics Induced EMF MCQ Question
Type: MCQ-numerical-Hard-Class 12
A big circular coil of 1000 turns and average radius 10 m is rotating about its horizontal diameter at 2 rad s⁻¹. If the vertical component of earth’s magnetic field at that place is 2 × 10⁻⁵ T and electrical resistance of the coil is 12.56 Ω, then the maximum induced current in the coil will be:
A
1 Å
B
2 Å
C
0.25 Å
D
1.5 Å
Correct Answer
Option A
Detailed Explanation
The maximum induced emf is given by E = NBAω. Substituting the given values and using Ω's law, the maximum current is 1 Å.
