A rectangular coil of 300 turns has an average area of 25 cm
10cm. The coil rotates with a speed of 50 cps in uniform magnetic field of strength 
about an axis perpendicular to the field. The peak value of the induced emf is (in volt)
- 300
- 3000
- 3
- 30
The correct answer is: 30
Peak value of induced emf in a rectangular coil is
