A generator has a 100-turn coil that rotates in a 0.30-T magnitude B-field at a frequency of 80 Hz. The area of each loop is 0.0

03 m2. Assume the coil plane is parallel at time is equal to 0. Determine the emf magnitude (in V) when time is 0.0140 s. Use 3 significant figures for answer.

Answer:

Explanation:

Flux Φ = nBA sinωt

t = 0 , flux = 0

dΦ / dt = nωBA Cosωt

e = nωBA Cosωt

= 100 x 2πx80 x.3 x .003 cos 2πx80 x .014

= 45.21 cos 7.0336

= 33.0668 v

= 33.1 V
