Abstract

1. Composite magnetic circuit consisting of at least two parts (11, 12) made of soft magnetic alloy, each of the parts (11, 12) consisting of a nickel-iron alloy of very high permeability containing more than 75% of nickel by weight and at least one element from the group of molybdenum, copper and chromium and having a maximum relative impedance permeability measured at 50 Hz of at least 200 x 10**3 G/Oe (0.25Tm/A), characterized in that the said parts have different curves of relative impedance permeability as a function of the temperature of measurement around the ambient temperature.
