A magnetoresistive sensor uses the fact that the electrical resistance in a ferromagnetic thin film alloy is changed through an external magnetic field. “Ferrum ...
This paper reviews magnetoresistive sensors for detecting magnetic fields. These sensors are based on an effect which has been known for more than 100 years ...
The magnetic fields may therefore carry information on properties such as direction, presence, rotation, angle, or electrical currents that is converted into an ...
They detect changes, or disturbances in magnetic fields that have been created or modified by objects or events. The magnetic fields may therefore carry ...
