1. Method for stabilizing the operating point of a Hall crystal (11) which is located in a magnetic field of variable strength (B) and is supplied with electrical energy from a supply source (12), in which the Hall crystal (11) is supplied via a series resistance (31) from a constant voltage source (30) and the power loss (P) of the Hall crystal is determined and stabilized, characterized in that the dependence of the normalized value (R/Ro ) of the resistance (32) of the Hall crystal (11) on the strength (B) of the magnetic field in its operating range (21) of interest is determined as a formula, that, taking into consideration this dependence, the dependence of the variation of the power loss (P) in the Hall crystal (11) on the strength (B) of the magnetic field in its operating range (21) of interest is determined with parametrization of epsilon = Z/Ro , that is to say of the ratio of the value (Z) of the series resistance (31) and of the value (Ro ) of the internal resistance (32) of the Hall crystal (11) with a magnetic field of strength zero, that furthermore the value (Z) of the series resistance (31) is optimized for minimum variation of the power loss (P) and that, finally, the Hall crystal (11) is operated in series with a series resistance (50) of this optimized value (Zopt ) from the constant voltage source (30).
