Mutual induction is a term that is widely used in the electrical and electronics industry. It refers to the phenomenon of producing an electrical current in a conductor by placing it near another conductor that is carrying an alternating current. There are several synonyms for mutual induction that are used in the industry such as electromagnetic induction, transformer coupling, and inductive coupling. Electromagnetic induction is the most commonly used synonym and is often used interchangeably with mutual induction. Transformer coupling is a synonym for mutual induction, but it refers specifically to the process as it occurs inside a transformer. Inductive coupling is simply a more general term that describes the phenomenon of mutual induction in any electrical device.
