Magnetostriction refers to ferromagnetic materials, commonly referred to as ferromagnetic magnetostrictive materials, that when an object is magnetized in a magnetic field, it elongates or contracts in the direction of magnetization, and changes its size significantly when the current through the coil changes or changes its distance from the magnet. The material is called a giant magnetostrictive material because its dimensional change is much larger than that of a magnetostrictive material such as ferrite and the like and the energy generated is also large. The electric guitar strings mostly use nickel plating to wind the strings, and some high-end strings also use iron nickel cobalt alloy as the string material. From the phonation principle of electric guitar say, the adapter is generally made by iron cobalt nickel magnetism post or ceramic magnetism post outside winding coil and is formed, and the string is installed after, is magnetized by the adapter, and then has produced magnetic field, because the popularization of this kind of magnetized characteristic and nickel iron cobalt alloy string, very easily just produced the magnetic stretching effect between string and the adapter.
