What is a Magnetometer?

A magnetometer is a device that can measure the strength of a magnetic field. It is possible to measure the strength and direction of the magnetic field, and there are various magnetometers depending on the environment in which it is used. For example, those that use the Hall effect and those that use electromagnetic induction. Magnetic field measurement has long been used to search for veins and is still used in various situations. It may be used for magnetic inspection during the manufacturing process of a product, or it may be incorporated into medical equipment and used as an inspection device.

Application of Magnetometer

Magnetometers are used in various situations to measure magnetic fields. Specifically, the following cases. Detection of magnetism buried underground It is used to find veins and to remove land mines buried in the ground. Medical equipment for inspection By measuring the magnetic field of the body, it can also be applied to the examination of magnetocardiography and magnetoencephalography. Non-destructive inspection equipment It is also used as a non-destructive inspection device. Damage and defects can be found by examining ferromagnets such as metals.
