Answer:
39.56 x 10⁻² V
Explanation:
Peak emf in a rotating coil
= n BAω
Where n is no of turns of coil , B is magnetic field , A is area of coil and ω is angular velocity of rotation of coil
Here n = 1
B = .21 T
A = 5 X 12 X 10⁻⁴ = 60 X 10⁻⁴
ω = 2π X 50 = 100π
Emf = 1 x .21 x 60 x 10⁻⁴ x 100 x 3.14
= 39.56 x 10⁻² V
