^ac generator
Also called dynamos or electric oscillators or commutators is based on EMI. When a metallic – coil is rotated at a high speed in a strong magnetic field, due to the change in magnetic flux linked with the coil a voltage difference ε = ε0 sin ωt, ε0 = BANω is induced across the two ends of the coil connected to the rings R1 & R2 called Slip rings, which when fed to external load through carbon brushed B1 & B2 can supply current to load.
