Аннотация:A magnetometer is described which allows the radio-engineering null method to be used to measure the magnetic moment of strongly magnetic substances by means of a capacitive displacement pickup in an electromagnet and in a solenoid over a wide temperature range 4. 2-1500 degree K. The variation of the capacitance as a result of the action of the ponderomotive force is monitored according to the unbalance of the capacitive bridge by a sensing amplifier.
