Abstract

In order to provide the parameter basis for the design of the walking energy collector

a method is proposed to study the coupling characteristics of the magnetic actuator of the magnetostrictive material. By observing the law of the angle deflection of the magnetic field

the magnetic coupling characteristics of the magnetostrictive material is studied

the best external magnetic field and the value of stress selected

and the external magnetization produced by the magnetostrictive material calculated. It is found that the increase of external magnetic field is beneficial to the deflection and transition of magnetic domain. However

the stress anisotropy can be detrimental to the magnetization of the giant magnetostrictive material

making the magnetization of the magnetostrictive material more difficult.
