Question

In a model AC generator, a 501 turnrectangular coil 10.0 cm by23 cm rotates at 123 rev/min in a uniform magnetic field of0.6 T. (a) What is the maximum emf induced in thecoil?
1 V
(b) What is the instantaneous value of the emf in the coil att = (/32) s?Assume that the emf is zero at t = 0.
2 V
(c) What is the smallest value of t for which the emf willhave its maximum value?
3 s (a) What is the maximum emf induced in thecoil?
1 V
(b) What is the instantaneous value of the emf in the coil att = (/32) s?Assume that the emf is zero at t = 0.
2 V
(c) What is the smallest value of t for which the emf willhave its maximum value?
3 s

----------

No.of truns N = 501

Area A= 10 cm * 23 cm = 230 cm^ 2= 230 * 10 ^ -4 m^ 2

Angular speed w= 123 rev / min

Magnetic field B = 0.6 T

So, Induced emf E = BANw
