“It’s sobering to think that in just a few weeks Derek Jeter won’t be doing any of this anymore, and will be reduced to picturing himself in action, just the way the rest of us do,” Roger Angellwrites.

When a magnetic field moves through a conductor a current called an Eddy current is induced in the conductor due to the magnetic field’s movement. The flow of electrons in the conductor creates an opposing magnetic field to the magnet which results in damping of the magnet and causes heating inside of the conductor similar to heat buildup inside of power cords. The loss of energy used to heat up the conductor is equal to the loss of kinetic energy by the magnet.
