Abstract
An integrating magnetic sensor is described which comprises a sensor element made from a filament of substantially amorphous material which exhibits giant magneto-impedance and means for applying a bias field to the said sensor element so that it operates in the high field section of the giant magneto-impedance response.
Claims10
A magnetic field sensor, said sensor comprising:
- an elongate sensor element component made of a substantially amorphous material which exhibits giant magneto-impedance (GMI);
- and
- bias means for biasing a field applied to said component to operate in the high field section of the GMI response.
