Question: Which of the following statements best describe electromagnetic induction?
Electromagnetic induction is a fundamental principle of physics that involves the generation of an electromotive force (EMF) across an electrical conductor in a changing magnetic field. This phenomenon was discovered by Michael Faraday in 1831 and can occur in two scenarios: when a conductor is placed within a moving magnetic field or when a conductor moves through a stationary magnetic field. The induced EMF generates a current, which is the basis for many applications in modern technology, such as electrical generators and transformers. Mathematically, the induced voltage in a coil is proportional to the number of turns in the coil and the rate of change of the magnetic field through the coil, described by Faraday's law of induction. This discovery has had a profound impact on the way we harness and utilize electrical energy today.
