Date Apr. 20, 1989.In a magnetometer with an inhomogeneous magnetic field which timewise changes in its intensity periodically and acts upon the specimen to be measured, the latter being attached to the free end of a tongue (8) that can be oscillated and whose oscillations can be determined by piezo elements (12, 13), there occurs a compensation of the magnetic moment of the specimen with the aid of a compensating current loop (33). The current required for arresting the oscillations is a measure of the magnetic moment to be determined. An adaptation to the resonance frequency of the oscillating tongue (8) is effected through a frequency control cirucit (22, 28, 6), making it possible to measure large temperature ranges at great sensitivity and contingent on temperature.
