What is Faraday's law of electromagnetic induction?

Faraday's law of electromagnetic induction states that a changing magnetic field induces an electromotive force (EMF) in a conductor.

This law is based on the principle that a magnetic field can induce an electric current in a conductor, and vice versa. Faraday's law states that the magnitude of the induced EMF is proportional to the rate of change of the magnetic field. This means that the faster the magnetic field changes, the greater the induced EMF will be.

The law also states that the direction of the induced EMF is such that it opposes the change in the magnetic field that produced it. This is known as Lenz's law, and it is a consequence of the conservation of energy.

Faraday's law has numerous practical applications, including in generators, transformers, and motors. It is also the basis for many modern technologies, such as wireless charging and wireless power transfer.

Understanding Faraday's law is essential for anyone studying electromagnetism or electrical engineering. It provides a fundamental understanding of how electricity and magnetism are related, and how they can be used to create useful devices and technologies.
