Introduction

Magnetoresistance sensors are advanced devices that detect changes in electrical resistance caused by an external magnetic field. These sensors utilize the magnetoresistance effect—where a material’s resistance varies with magnetic field intensity—to precisely measure magnetic fields, position, and speed. With their high sensitivity, compact size, and low power consumption, magnetoresistance sensors are widely used in automotive systems, industrial machinery, consumer electronics, and data storage devices.
