A coil of 200 turns and radius 0.1 m is rotated at 50 revolutions per second in a magnetic field of 0.2 T. What is the maximum induced EMF?
Q1. A coil of 200 turns and radius 0.1 m is rotated at 50 revolutions per second in a magnetic field of 0.2 T. What is the maximum induced EMF?
Answer: 1256 V
Explanation: ε = NABω = 200 x π x (0.1)² x 0.2 x 2π x 50 = 1256 V. Option B is wrong due to incorrect ω.
