Web2 de dez. de 2024 · Eddy Current. Eddy currents flow through conductors like whirling eddies in a stream, and they are frequently formed in reaction to a changing magnetic field. They flow in closed loops perpendicular to the plane of the magnetic field plane, caused by changing magnetic fields. These are also known as Foucault’s Currents. WebEddy current magnitude can be reduced by designing the core as a set of thin sheets or laminations, in parallel to the magnetic field. Each sheet must be insulated from its neighbours with a thin coating of varnish or oxide film. By laminating the core, the area of each section and hence the induced EMF is reduced.
