A Magnetic Sensors is a piece of equipment that recognises disturbances and adjustments to the flux, flux direction, and strength of a magnetic field. The qualities of light, pressure, and temperature are only a few examples of how detection sensors may operate. Control technology use magnetic sensors to find wear-free and contactless areas. In situations where inductive sensors have reached their limits, they are very helpful. The sensors are small, have large sensing areas, and can detect objects within a few millimetres to a few centimetres. The lifespan of magnetic sensors is very lengthy, and they are incredibly robust.

They are wear-free, contactless, and omnipolar (can detect both the north and south poles) because they don't have any moving parts. The strength, direction, and magnitude of magnetic fields are measured using a variety of magnetic sensors. Single resistors and spaced resistors are the components of these sensors. Magnetic Sensors are applied in situations where strong magnetic fields are present. Additionally, magnetic sensors are used in biomedical applications. Researchers can determine the permeability of free space by measuring changes in a magnet's location. In Tesla, magnetic induction is measured. Magnetic induction can also be measured using solid state magnetic sensors.
