What is electromagnetic induction in physics?

Question

William Audy · Accepted Answer

When a moving conductor(like copper or iron) placed in the magnetic field,then an emf is induced in an electrical conductor.
This is called electromagnetic induction.

Without the application of voltage (emf), there would be no electricity since it is necessary to drive the current. In summary, voltage must be applied in order to drive current. Where is the voltage coming from? How can we give extremely tiny electrons a moving force? Principle: When a moving conductor (such as copper or iron) is placed in a magnetic field, the moving conductor is cut by magnetic lines. If the moving conductor is cut by magnetic lines, an induced magnetic field (emf) is created in the conductor, which further drives the current when a closed circuit is provided. #or#

undefined Electromagnetic induction is the process by which a changing magnetic field induces an electromotive force (EMF) or voltage in a conductor. This phenomenon was first discovered by Michael Faraday in 1831. It is governed by Faraday's law of electromagnetic induction, which states that the induced EMF in a circuit is proportional to the rate of change of magnetic flux through the circuit. Electromagnetic induction is the principle behind the operation of electric generators, transformers, and inductors, and it plays a crucial role in many aspects of modern technology.
