Question 2
1 / -0

Kamla peddles a stationary bicycle the pedals of the bicycle are attached to a 100 turn coil of area 0.10m². The coil rotates at half a revolution per second and it is placed in a uniform magnetic field of 0.02 T perpendicular to the axis of rotation of the coil. What is the maximum voltage generated in the coil?

A
0.554 V

B
0.628 V

C
0.714 V

D
0.314 V

Solution

Maximum voltage is given by:

e₀= N B Aω

but, ω = 2πn = 2 × 3.14 × 0.5
Therefore, e₀= N B Aω = 100 × 0.02 × 0.1 × 2 × 3.14 × 0.5 = 0.628V
