Mutual induction occurs between what in electrical circuits?

Mutual induction happens when two coils or conductors share magnetic linkage. When the current in one coil changes, its magnetic field changes and the magnetic flux links the nearby coil. That changing flux induces a voltage in the second conductor through Faraday’s law. This is the principle behind transformers, where energy is transferred between windings that are magnetically coupled. It’s different from self-induction, which occurs within a single coil, and from a capacitor or resistor, which don’t involve magnetic coupling between separate conductors. The induced voltage in the second coil can be described by e2 = -M di1/dt, where M is the mutual inductance.
