Q. The 50-turn coil in the configuration of Figure is rotated at a constant speed of 300 r/min. The axis of rotation is perpendicular to a uniform magnetic flux density of 0.1 T. The loop has width w = 10 cm and length l = 1m.
Compute:
(a) The maximum flux passing through the coil.
(b) The flux linkage as a function of time.
(c) The maximum instantaneous voltage in- duced in the coil.
(d) The time-average value of the induced volt- age.
(e) The induced voltage when the plane of the coil is 30° from the vertical.
