The invention relates to a method and an apparatus for regulating a current through an inductive load, which can be connected to a power supply, to a prescribed nominal current value, where the method comprises the following method steps: a) turning on and off the power supply in pulsed fashion, with the power supply being turned on when the current (I) flowing through the load (L) reaches a first limit value (I<SUB>-</SUB> 1 ), which is below the nominal current value (I_nominal) by a hysteresis value (H), and with the power supply being turned off when the current (I) reaches a second limit value (I<SUB>-</SUB> 2 ), which is above the nominal current value (I_nominal) by the hysteresis value (H), b) determining a period duration between two successive turn-on or turn-off times, c) comprising determined the period duration with a given period duration (Tnominal), and d) changing the hysteresis value (H) on the basis of the comparison between the determined period duration and the prescribed period duration (Tnominal).
