Abstract (en)

[origin: WO2012054000A1] The method for measuring magnetic field includes measuring the output voltage of the galvanomagnetic transducer and calculation induction of the measured magnetic field according to the measured values of the output voltage and sensitivity of the galvanomagnetic transducer; herewith, the galvanomagnetic transducer contains, at least, two pairs of leads, and measurements are carried out in two stages - at the first stage the first pair of leads is used to supply power to the galvanomagnetic transducer, while the other pair is used to measure the output voltage; at the second stage the first pair of leads is used to measure the output voltage, whereas the other pair is used to supply power to the galvanomagnetic transducer. Sensitivity of the galvanomagnetic transducer is found, at least at one of the above stages by measuring at least two values of the output voltage, the first of which is caused by the action of measured magnetic field only, and the second is caused by the sum of the measured magnetic field and the test field, whose magnitude is given in advance.
