An AC generator consists of 6 turns of wire. Each turn has an area of 0.040 m². The loop rotates in a uniform field (B = 0.20 T) at a constant frequency of 50 Hz. What is the maximum induced emf? A) 13 V B) 2.4 V C) 3.0 V D) 15 V E) 4.8 V

Question

Quizplus · Accepted Answer

The maximum induced emf can be calculated using the formula:

emf = NBAω

where N is the number of turns, B is the magnetic field strength, A is the area of each turn, ω is the angular frequency (2πf) and f is the frequency.

Substituting the given values, we get:

emf = 6 * 0.040 * 0.20 * 2π * 50

emf = 15.08 V

Therefore, the maximum induced emf is 15 V, which is closest to choice D.
