Magnetic Field Sensors

Magnetic field sensors are electronic devices that measure the strength and direction of magnetic fields and convert them into a measurable electrical signal. They are commonly used in a variety of applications, such as navigation, automotive, industrial, and medical.

Magnetic field sensors work by detecting the change in magnetic field strength or direction as a magnetic field interacts with a sensing element. The sensing element is typically a small piece of magnetic material, such as a magnetoresistive or Hall-effect sensor, which generates a measurable electrical signal proportional to the strength and direction of the magnetic field.

There are several types of magnetic field sensors, including Hall-effect sensors, magnetoresistive sensors, and fluxgate sensors. Hall-effect sensors work by measuring the change in voltage across a thin strip of semiconductor material as it is exposed to a magnetic field. Magnetoresistive sensors work by measuring the change in resistance of a thin film of magnetic material as it is exposed to a magnetic field. Fluxgate sensors work by using a coil to detect the magnetic field and a feedback circuit to measure the strength and direction of the field.
