An analysis of the fundamental possibility of creating mathematical models of EMPE, which, in the two-dimensional approximation of a quasi-steady-state magnetic field, will adequately consider the losses from eddy currents in the laminated elements of the magnetic conductors in both the established and transient operating modes.
This makes it possible to accurately compute the size of eddy current loss, which is the primary cause of ferrite magnetic loss.
The M Pumps hybrid solution 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.
Because eddy currents mostly flow on the surface of the metal test piece, a crack will disturb the magnetic field lines and show up as a change in the probe's apparent resistance and inductance.
Thus, the induced eddy currents and their associated magnetic field exert a counteracting force upon the source of the initial magnetic field.
