What is Electromagnetic Induction?
Electromagnetic Induction was discovered by Michael Faraday in 1831 and James Clerk Maxwell mathematically described it as Faraday’s law of induction.
Electromagnetic Induction is a current produced because of voltage production (electromotive force) due to a changing magnetic field.
This either happens when a conductor is placed in a moving magnetic field (when using AC power source) or when a conductor is constantly moving in a stationary magnetic field.
Michael Faraday arranged a conducting wire as per the setup given below, attached to a device to measure the voltage across the circuit. When a bar magnet was moved through the coiling, the voltage detector measures the voltage in the circuit.
Explanation:
Electromagnetism is a branch of Physics, that deals with the electromagnetic force that occurs between electrically charged particles. The electromagnetic force is one of the four fundamental forces and exhibits electromagnetic fields such as magnetic fields, electric fields, and light.
