Question

A rectangular coil of 300 turns has an area of
25 cm x 10 cm. The coil rotates with a speed
of 50 cps in a uniform magnetic field of
strength 4 x 10^-2 T about an axis perpendicular
to the field. The peak value of the induced
e.m.f is (in volt)
1) 3000 pi 2) 300 pi 3) 30 pi 4) 37 pi​

Answer 1

Explanation:

E = NBAw

E= 300*10*25*10^(-4)*50*2π*4x10^(-2)

E = 30π
