The induced emf in a coil rotating in a magnetic field is maximum when the angle between the coil's plane and the field is?
Q1. The induced emf in a coil rotating in a magnetic field is maximum when the angle between the coil's plane and the field is?
Answer: 90°
Explanation: Emf is maximum when the coil is perpendicular to the field, maximizing the rate of change of flux. Option A fails because at 0°, the flux change is minimal.
