An emf is generated by an ac generator having 100 turn coil, of loop area 1m2. The coil rotates at a speed of one revolution per second and placed in a uniform magnetic field of 0.05 T perpendicular to the axis of rotation of the coil. The maximum value of emf is
- 62.8 V
- 6.28 V
- 3.14 V
- 31.4 V
Answer
(D) 31.4 V
