Question

What does a time varying magnetic field yield?

Answer 1

Faraday's law of electromagnetic induction, commonly known as Faraday's law, is a fundamental rule of electromagnetism that explains how a magnetic field interacts with an electric circuit to generate an electromotive force (EMF). Electromagnetic induction is the term for this phenomenon. In the year 1831, Michael Faraday proposed the laws of electromagnetic induction. Faraday's law, often known as the law of electromagnetic induction, is the consequence of Faraday's experiments. To uncover the phenomena of electromagnetic induction, he conducted three major experiments.

Complete answer:
Faraday deduced from his experiments that as the magnetic flux across the coil varies with time, an emf is produced in the coil. As a result, Faraday's first rule of electromagnetic induction says that an electromotive force is produced whenever a conductor is put in a changing magnetic field. A current is induced when the conductor circuit is closed, and this is known as induced current.
In a closed loop, there are a few techniques to modify the magnetic field intensity:
The coil is rotated in relation to the magnet.
The coil is moved into and out of the magnetic field.
By adjusting the size of a coil in a magnetic field.
By moving a magnet in front of or behind the coil.
An electric field is created by a time-varying magnetic field. When magnetic flux varies in the region around a conductor, it produces an electric field (induced emf) in the conductor, according to Faraday's law. A time-varying magnetic field causes flux to fluctuate, resulting in an electric field.

Note:
The induced emf in a coil is equal to the rate of change of flux linkage, according to Faraday's second law of electromagnetic induction. An electric field is created by a time-varying magnetic field. According to Faraday's law, an electric field is created when the magnetic flux associated with a conductor changes.
