"A water-cooled coil (inductor), acting as the primary winding of a transformer, surrounds the material to be heated (the workpiece), which acts as the secondary winding. Alternating current flowing in the primary coil induces eddy currents in the workpiece, causing it to become heated."
Because of their general circulatory nature, these are referred to as eddy currents.
Near-field eddy currents in small planar inductance coils
eddy currents in attraction type motor
The higher the face velocity, the greater the eddy currents.
To diminish the influence of the eddy currents, the design method of self-shielded gradient coils is studied and the self-shielded uniplanar gradient coils are designed in this paper.
Potholes are developed in the solid rock of the bed by pebbles and boulders swirling around in eddy currents.
