Question

The rotating loop in an AC generator is a square 10.0 cm on a side. It is rotated at 55.0 Hz in a uniform field of 0.800 T. Calculate the following quantities as functions of time t, where t is in seconds.

(a) the flux through the loop
mT·m²
(b) the emf induced in the loop
V
(c) the current induced in the loop for a loop resistance of 2.00 Ω
A
(d) the power delivered to the loop
W
(e) the torque that must be exerted to rotate the loop
mN·m
