Eddy currents. Overview. A magnet levitates over a rapidly spinning aluminum disc. As a control experiment, a brass nut may be used to demonstrate that the levitation is an eddy current effect.

Eddy currents, also called Foucault current, are loops of electrical current induced within a conductor by a time-varying magnetic field in that conductor (Figure 1). This phenomenon of induction was ...

A magnet falling down a copper tube is slowed by magnetic fields from eddy currents induced in the tube. A magnet falling down a glass tube is unaffected. Set up lab stands, each with a 3-finger clamp ...
