Explain the process of electromagnetic inductio... - SS1 Physics Magnetism and Electromagnetism Question

Electromagnetic induction is the process of producing an electric current in a conductor by changing the magnetic field around it. When a conductor, such as a wire, is exposed to a changing magnetic field, an electromotive force (emf) is induced in the conductor, which causes an electric current to flow. This phenomenon was first discovered by Michael Faraday.

The basic principle behind electromagnetic induction is Faraday's law, which states that the magnitude of the induced emf is directly proportional to the rate of change of the magnetic field. This induced current can be utilised to generate electricity in devices like generators, where a rotating magnet or electromagnet is used to create a changing magnetic field relative to the conductor.
