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. The disc spins at several ...

A nondestructive testing technology called eddy current array (ECA) is capable of driving numerous eddy current coils that are positioned next to one another in the same probe assembly. In the probe, ...

Eddy currents are specialized electric fields that are generated in the presence of a magnetic field and are often seen as a secondary field. An Eddy current can be produced by both electromagnets and ...

The description of an eddy current separator (ECS) sounds like the wrong answer to a science quiz: How can it use magnets to repel, rather than attract? And how can it affect nonmagnetic metals like ...
