Summary:A magnetometer 100, for determining an external magnetic field, comprises a magnetoresistive material forming, an electrode arrangement 104, and a processor. A resistive response of the magnetoresistive material comprises a decreasing response for a first range of increasing applied external magnetic fields, and an increasing response for a second range of increasing applied external magnetic fields. The electrode arrangement 104 measures the resistive response of the magnetoresistive material to the applied external magnetic field. The processor is configured to determine if the external magnetic field applied to the magnetoresistive material is in the first range or in the second range. The processor is configured to determine the external magnetic field based at least partly on the resistive response of the magnetoresistive material to the external magnetic field and whether the external magnetic field is in the first range or in the second range.
