Multiple Choice

If two coils influence each other in a circuit, this effect is called:

The effect at play is the magnetic coupling between two coils, where a changing current in one coil induces a voltage in the other. This phenomenon is called mutual induction. It happens because the changing current in the first coil creates a changing magnetic flux that links the second coil, generating an electromotive force there. This differs from self-induction, where a coil’s own changing current induces voltage in itself. Capacitve coupling involves electric fields and capacitance between conductors, not magnetic coupling between coils, and resistive coupling means current influence through resistance rather than induction.
