Electromagnetic or magnetic induction is the production of an electromotive force (emf) across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday''s law of induction .

The answer is that the two plates of a capacitor store the same amount of charge but with opposite signs. That means that the capacitor is actually neutral, even when it is said to store a large amount of charge! If you could probe the space between the capacitor plates, you would feel electric forces because each plate individually is charged.
Single-phase induction motors can be controlled using three main methods, Capacitor-start, Capacitor-run, and Capacitor-start-capacitor-run.
