A circular loop with 30 turns and area of 0.25 m2 rotates at 100 rad/s. The axis of rotation of the loop is perpendicular to the direction of the magnetic field of 0.04 Tesla. What is the maximum emf induced in the loop?

e = 30 V

Explanation:

given,

N = 30 turns

Area = 0.25 m²

angular speed = ω = 100 rad/s

Magnetic field = 0.04 T

maximum induced emf in the loop = ?

e = N B A ω

e = 30 x 0.04 x 0.25 x 100

e = 30 V

hence, the maximum emf induced in the loop is equal to e = 30 V
