Abstract
A method for measuring a first magnetic field and the temperature of a magneto-resistive transducer includes producing, by the magneto-resistive transducer, a measurement signal dependent on the intensity of the first magnetic field and on the temperature of the magneto-resistive transducer. The method includes establishing a measurement of the intensity of the first magnetic field on the basis of the measurement signal produced and a measurement of the temperature of the magneto-resistive transducer. The method also includes generating a second magnetic field to combine with the first magnetic field to form a resultant magnetic field. The method further includes extracting from the measurement signal, the component which is dependent solely on the second magnetic field and establishing the temperature of the magneto-resistive transducer on the basis of the component extracted.
