In mutual induction, what passes between conductors to create voltage?

Explanation:
Mutual induction relies on a changing magnetic flux linking the two conductors. When the current in the first conductor changes, it creates a magnetic field whose flux through the second conductor changes as well. This changing flux induces a voltage in the second conductor (Faraday’s law: EMF = -N dΦ/dt). The carrier here is the magnetic flux linking the circuits, not radiation, a direct current passing between them, or resistance. The induced voltage depends on how quickly the flux changes and how well the two circuits are magnetically coupled.
