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 ...

At some point during our primary school careers, most of us probably constructed a simple compass, often by floating a magnetized needle on a cork in a cup of water. The water in such a configuration ...

In 1851 when French physicist Léon Foucault discovered the magnetic repelling phenomenon that is used in eddy current separators, he likely did not envision the wide variety of applications in which ...

A magnetic field is generated by a 240-volt, 20-to-30-amp, 20-to-75-kHz-frequency electric current from a 40- or 50-amp breaker through a copper coil. Magnets pull otherwise randomly distributed ...

[Tim Williams] made his own induction furnace. A copper tubing coil forms the primary winding, as the material to be heated becomes the short circuited secondary. The load material is subject to high ...
