Question

What is actually happening when a magnetoresistive magnetometer degausses itself?

Answer 1

Hey mate ^_^

Rotation of the sensor should vary the output voltage...

If it does not, the part maybe "permed" due to strong magnetic fields over 20 gauss such as accidental proximity of magnetized tips of some hand tools during assembly....

Performing the application of current pulses across the set/reset strap should degauss the sensor(s) and restore performance....

Answer 2

Hello mate here is your answer.

Magnetometers can be used as metal detectors: they can detect only magnetic (ferrous) metals, but can detect such metals at a much larger depth than conventional metal detectors; they are capable of detecting large objects, such as cars, at tens of metres, while a metal detector's range is rarely more than 2 metres.

Hope it helps you.
