How to create Eddy currents? Magnet Blog News IMA

Eddy currents are electrical currents which, using an eddy current separator, can cut even the smallest non-ferrous metals. +44 203 318 75 73 [email protected]


Eddy Currents K&J Magnetics Strong Neodymium

A popular setup for eddy current brakes is to set two strong magnets with a gap between them. This creates a strong magnetic field between the two magnets, as described previously in our Gap Calculator article. If this magnet pair is placed on either side of a spinning disc, the eddy currents induced in the metal will act to slow it down.
