SUMMARY
The maximum electromotive force (emf) induced in a rotating coil can be calculated using the formula Emax = NBAω. In this discussion, a 104-turn coil rotating at 7.14 revolutions per second, with a cross-sectional area of 0.670 m² and a magnetic field strength of 0.0720 T, yields a maximum emf of 35.82 V. The key takeaway is that the induced voltage varies as the coil rotates, affecting the area exposed to the magnetic field while the magnetic field strength remains constant.
