A 100 turn coil of area 0.1 m^2 rotates at half a revolution per secon

1.	A 100 turn coil of area 0.1 m^2 rotates at half a revolution per second. It is placed in a uniform magnetic field of 0.01 T perpendicular to the axis of rotation of the coil. Calculate the maximum voltage generated in the coil?(a) 256.33 V(b) 89.12V(c) 0.314 V(d) 3.1455 VI have been asked this question in a job interview.My question is based upon AC Generator topic in chapter Alternating Current of Physics – Class 12
Answer» The CORRECT ANSWER is (c) 0.314 V Explanation: The maximum VOLTAGE generated in the coil, e0 = nBAω e0 = NBA × (2πv) e0 = 100 × 0.01 × 0.1 × 2π × 0.5 e0 = 0.314 V
