Faraday's Experiment

Faraday’s experiment

Faraday’s experiment, also known as Faraday’s induction experiment, was a series of experiments performed by the British scientist Michael Faraday in 1831. The experiments demonstrated the relationship between a changing magnetic field and an induced electric current.

Faraday discovered that if a magnet is moved near a closed loop of wire, an electric current is induced in the wire. The amount of induced current depends on the strength of the magnet, the speed of the movement, and the number of turns in the wire.

In his famous experiment, Faraday took a coil of wire and connected it to a galvanometer, which is an instrument that measures electric currents. He then moved a magnet toward the coil, causing the galvanometer to show a momentary deflection, indicating the presence of an induced electric current in the coil.

Faraday also discovered that the direction of the induced current depends on the direction of the movement of the magnet, as well as the orientation of the magnet with respect to the coil.

This experiment demonstrated that a changing magnetic field can produce an electric current, which led to the development of electric generators and motors. Faraday’s work on electromagnetic induction was a major breakthrough in the field of electromagnetism and had a significant impact on the development of modern technology.
