The operating principle of mag-drive pumps involves a rotating magnetic field which is separated by a stationary metallic barrier which cuts the magnetic field and generates eddy currents that in turn generate heat.
The M Pumps hybrid design minimises magnetic losses by featuring a very thin barrier (in either Hastelloy or titanium), with a thin carbon outer shell, thereby reducing the amount of heat from eddy currents and the distance between the rotating magnets.
If the coil (probe) is brought close to a metal surface with the B field perpendicular to it, eddy currents will be induced in the metal.
When a conductive part is moving perpendicular through a time-varying or an inhomogeneous magnetic field, an electric field is induced, which in turn generates eddy currents within the conductive material according to Faraday's law of induction.
The implementation of eddy currents in the industrial sector are proven and established.

Figure 11(a) shows the circulating eddy currents in the non-segmented pieces of the V-shaped pole magnet, (b) shows the same in the segmented pieces.
With an eddy current instrument eddy currents are induced in a specimen when an alternating current, which is generated by the instrument, is applied to a test probe.
The knowledge of eddy currents and power losses allows the estimation of optimal supply frequency.
The system, which is designed to greatly increase the capacity of the shredder's nonferrous product, will include new screens and eddy currents and a stainless steel separator supplied by Huron Valley Magnetics Division, Trenton, Mich.
