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 ...

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 ...

Over the last 40 years, permanent-magnet couplings have come into the manufacturing forefront. This technology can operate at high speeds without contact or wear of active components, and at ...

THE well-known Larmor analogy between the deflecting force exerted by a magnetic field upon the motion of electrically charged bodies and the Coriolis force which similarly deflects a moving body ...

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 ...

The wide-band, high-sensitivity MBN measurement system presented in this study has clarified the physical origin of excess eddy current losses in soft-magnetic materials, offering crucial insights for ...

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 ...

Lenz’s Law is one of those physics tricks that look like magic if you don’t understand what’s happening. [Seth Robinson] was inspired by the way eddy currents cause a cylindrical neodymium magnet to ...
