In this video I experiment with Lenz’s Law And Faraday’s Law of Induction to generate electricity and magnetic force fields in copper.YouTuber NightHawkInLight got his hands on some thick copper plates and some neodymium magnets, then showed some of the strange ways the two materials interact.

This experiment uses Lenz’s Law and Faraday’s Law of Induction to generate electricity and magnetic force fields in copper. When a magnetic field moves through a conductor the movement induces an eddy current in the conductor.

The flow of electrons in the conductor immediately creates an opposing magnetic field which results in damping of the magnet and produces heat inside the conductor similar to heat buildup inside of a power cord during use.

The amount of energy transferred to the conductor in the form of heat is equal to the change in kinetic energy lost by the magnet – the greater the loss of kinetic energy of a magnet (a product of its mass and speed), the greater the heat buildup in the conductor and the more forceful the damping effect.
