D. The process of producing a voltage across a conductor when it is exposed to a varying magnetic field



Answer :

GinnyAnswer

Final answer:

Electromagnetic induction is the generation of a voltage in a conductor due to a changing magnetic field, explained by Faraday's law of induction.


Explanation:

Electromagnetic induction is the process by which a voltage is induced in a current-carrying conductor due to a changing magnetic field. This phenomenon is described by Faraday's law of induction and is a fundamental concept in electromagnetism. For example, when a coil of wire is moved through a magnetic field, it generates an electromotive force (emf) that causes a current to flow.
