What is the process of inducing a voltage in a conductor through a magnetic field called?

The process of inducing a voltage in a conductor through a magnetic field is known as electro-magnetic induction. This phenomenon occurs when a conductor, such as a wire, is placed within a changing magnetic field. According to Faraday's law of electromagnetic induction, the rate of change of the magnetic field through the conductor generates an electromotive force (emf), or voltage, across the ends of the conductor. This principle is fundamental to the operation of various electrical devices, including generators and transformers, where mechanical energy is converted to electrical energy or vice versa.

In contrast, capacitance refers to the ability of a system to store electric charge, relating to the electric field between conductors, but does not involve magnetic fields. Inductance, while related to the concept of magnetic fields, specifically deals with how an electrical current flowing through a conductor creates a magnetic field and how that field interacts with the circuit itself rather than inducing voltage through an external magnetic field. Current flux is not a recognized term in this context and does not represent a clear physical process related to voltage induction in conductors.
