An electromagnetic generator consists of a coil that has 100 turns of wire, has an area of 400 cm2, and rotates at 60 rev/ s in a magnetic field of 0.25 T directed perpendicular to the rotation axis. What is the magnitude of the emf induced in the coil?

Respuesta :

Answer:

376.8 Volt

Explanation:

N = 100, A = 400 cm^2 = 400 x 10^-4 m^2, B = 0.25 T, f = 60 rps

Maximum value of induced emf is given by

e = N x B x A x w

e = 100 x 0.25 x 400 x 10^-4 x 2 x 3.14 x 60

e = 376.8 Volt
