What Is an Electromagnetic Coupling?

Electromagnetic coupling is also called mutual inductance coupling. It is because of the mutual inductance between two circuits, so that the current change of one circuit affects the other circuit through mutual inductance. The phenomenon of close coordination and mutual influence between the input and output of two or more circuit elements or electrical networks, and the transmission of energy from one side to the other through interaction; in general, coupling refers to two entities A measure that depends on each other. ^[1]
