Therefore, a new dynamic model including load, disc spring stiffness, and friction is established based on combination of minor loops J-A model of GMM, structural dynamic equation of GMA, Ampere circuit law, and nonlinear piezomagnetic
equation through analyzing the working principle of GMA.

Materials and Their Function in Transducers.
Now common in new engineering structures, especially in smart materials and intelligent components, the emerging field of magnetostriction has developed in both single phase materials with electric and magnetic ordering and also in two-phase composites where participating phases are piezoelectric and piezomagnetic
Stress and magnetics are linked through a process called the piezomagnetic
effect, whereby stress can reorganize the magnetic structure inherent in certain minerals such as magnetite.
