Faraday induction

Faraday induction

Learning objectives

To illustrate a simple and historic experiment performed by Faraday in 1831 to study the laws of induction.
To emphasize that whether it is the magnet or the conducting loop that turns or moves, the effect is the same.
To introduce the problem of relativity that was resolved by Einstein 80 years later.

Induction occurs when the flux of B through a closed loop varies.

Keep in mind that this experiment is the basis for the principles underlying many power plants.

You can choose to move either the magnet or the conducting loop.
