What is Electromagnetic Induction?
Electromagnetic Induction is when a conductor is placed in a magnetic field and produces voltage throughout the conductor. It is used in many devices, such as generators, motors, television, and even credit cards. Credit cards, for example, contain a magnetic strip that has a series of magnets that is specific to that credit card. When swiped through a reader, it can identify the exact card by reading the position of the magnets.
