Hall element is a magnetic sensor based on the Hall effect, which can detect magnetic fields and their changes, and can be used in various magnetic field related situations. Hall elements have many advantages, such as sturdy structure, small size, light weight, long lifespan, easy installation, low power consumption, high frequency (up to 1MHz), vibration resistance, and resistance to pollution or corrosion from dust, oil, water vapor, and salt spray. Hall elements have a wide range of applications, such as signal sensors in automotive power distribution systems, speed sensors in ABS systems, speedometers and odometers, liquid physical quantity detectors, current detection and working status diagnosis of various electrical loads, engine speed and crankshaft angle sensors, various switches, and so on.

Before the invention of rare earth permanent magnet materials in the 1970s, AlNiCo aluminum nickel cobalt alloy had always been the strongest permanent magnet material in terms of magnetic properties. However, due to the strategic metals cobalt and nickel in its composition, the cost was relatively high. With the successive emergence of ferrite permanent magnets and rare earth permanent magnets, aluminum nickel cobalt materials were gradually replaced in many applications. However, in some high-temperature applications and situations where high magnetic stability is required, AlNiCo magnets still occupy an unshakable position.
