Abstract
A novel fluxgate magnetometer is introduced which employs the measurement of the change of the apparent coercive field strength derived from the magnetizing current. The external magnetic field is periodically measured at a frequency which is the same as that of the magnetizing current of the sensor. The magnetometer shows a standard deviation of the relative nonlinearity of less than 0.01% and a resolution of 0.1 nT, and it can measure transient external magnetic fields with a 100-kHz sampling rate
