DC Motor

DC Motor

Electric motors turn electricity into motion by exploiting electromagnetic induction.



A capacitor is similar to a battery in that both store electrical energy. But a capacitor can't actually produce new electrons; it only stores them.

Electromagnetic Induction

Electromagnetic Induction

In 1831, Michael Faraday carried out numerous experiments to prove that electricity could be generated from magnetism. He not only demonstrated electromagnetic induction, but also developed a good conception of the processes involved.
