It does so through a coil placed inside a spinning magnet. In turn, the coil causes a change in the flow law for electromagnetic electromagnetic dpstream induction causes an electromotive force (voltage). This voltage is AC, but thanks to a switch can easily be converted to DC.
and demonstration videos explaining:
b) If a return sencerad'una coil generates dpstream a sinusoidal voltage signal period and the dynamo is a generator DC, explains what item and how it switched? I replaced the rings connecting two semicylinder that revolve solidarity with the axis of the loop, so that changing the direction of the current induced change semicylinder also contact outside, ie brushes and so on get an external circuit dpstream pulsed current. Moreover, if instead of a single loop we put a group of loops connected to the collector slats get an almost constant current and therefore have a DC generator. Thanks switching brushes that make the collector slats in the external circuit current obtained.
