 Another type of magnetic field sensing device is the magnetic tag. Basically, the technology behind magnetic tags is the same as the one used in anti-theft alarm systems in shops, where simple inductor-capacitor circuits or magnetostrictive strips are excited by a fixed search coil. Magnetostriction is the change in the dimension of a material when subjected to an external magnetic field. Another type of magnetic field sensing device is the magnetic tag.
