Eddy current testing has been used for at least 50 years to inspect conductive parts for surface imperfections such as cracks or scratches. Fundamentally, the technique is comparative—it only ...

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 ...

Unlike mechanical brakes, which are based on friction and kinetic energy, eddy current brakes rely on electromagnetism to stop objects from moving. Eddy currents are created when a conductor passes ...

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 ...
