Find the induced emf across the coil, Electrical Engineering

Assignment Help:

Q. A coil is formed by connecting 15 conducting loops, or turns, in series. Each loop has length l = 2.5 m and width w = 10 cm. The 15-turn
coil is rotated at a constant speed of 30 r/s (or 1800 r/min) in a magnetic field of density B = 2 T. The configuration of Figure applies.
