<p>The Hall-effect component comprises, as a component belonging to a class having similar hysteresis loops, devices that are capable of subjecting groups of probes to a predetermined induction field, in the absence of perturbing systems situated in relation to the probes. This is carried out in such a way that a "vacuum" difference of induction, (BO) appears between the groups, a difference which is either at least greater than the upper switching threshold (BH), or at least less than the lower switching threshold (BB), or lies between the switching thresholds (BH and BB) so as to obtain a signal with a predetermined logical state at the output of the hysteresis-level comparator.
