Question

Figure 28-59 shows a schematic drawing of an ac generator. The basic generator consists of a rectangular loop of dimensions aa and bb and has NN turns connected to slip rings. The loop rotates (driven by a gasoline engine) at an angular speed of ω\omega in a uniform magnetic field B\overrightarrow{\boldsymbol{B}}. Verify that the induced potential difference between the two slip rings is given by E=NBabωsinωt\mathcal{E}=N B a b \omega \sin \omega t.
