Generate magnetic field via induction
WebAlternating current generating systems were known in simple forms from the discovery of the magnetic induction of electric current in the 1830s. Rotating generators naturally produced alternating current but, since there was little use for it, it was normally converted into direct current via the addition of a commutator in the generator. The early machines were … WebMar 13, 2024 · A 6 to 8 inch long piece of iron, such as a large nail or spike, will create a powerful magnetic field, but you can use smaller or bigger rods if you prefer.

WebSep 12, 2024 · Figure 13.7. 3: The emf of a generator is sent to a light bulb with the system of rings and brushes shown. The graph gives the emf of the generator as a function of time, where ϵ 0 is the peak emf. The period is T = 1 / f = 2 π / ω, where f is the frequency. The fact that the peak emf is ϵ 0 = N B A ω makes good sense.
