What term describes voltage induced in a conductor by changing magnetic fields from nearby lines?

The voltage produced in a conductor when nearby lines create a changing magnetic field is described by electromagnetic induction. A time-varying magnetic field induces an electric field that pushes charge along the conductor, generating an emf. This relationship is captured by Faraday’s law: emf is proportional to the rate of change of magnetic flux. Induction refers to this process itself. Inductance is a property of a circuit describing how changes in current produce voltage within the circuit, capacitance relates to storing energy in electric fields, and resistance is about opposition to current flow. So the phenomenon described is induction.
