A big circular coil of 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
- B
- C
- D
Solution & Step-by-step Explanation
Maximum induced EMF .Given: $
I_{max} = \frac{\epsilon_{max}}{R_{res}} $
I_{max} = \frac{\epsilon_{max}}{R_{res}} $
