Abstract

An inductor apparatus (2) includes an inductor winding (3), a core (4) defining a magnetic circuit (1) for a magnetic flux generated by a current flowing through the inductor winding (3), at least one permanent magnet (5) magnetically biasing the core (4) by its permanent magnetisation, and a magnetisation device operable for adjusting a desired magnetisation of the permanent magnet (5). The at least one permanent magnet (5) is arranged within the magnetic circuit (1) of the magnetic flux generated by the current flowing through the inductor winding (3). The magnetisation device includes a magnetisation winding (7) and a circuitry (13) operable for subjecting the magnetisation winding (7) to magnetisation current pulses (8) generating a magnetic field at a location of the permanent magnet which is able to change the permanent magnetisation of the permanent magnet.
