By application of a magnetic ﬁeld on an amorphous metallic strip, the orientation of magnetization of Weiss domains can be changed. When the strip changes its length, this effect is called magnetostriction. We simulate this effect using a ﬁnite element method. In particular we calculate the change of the mechanical resonance frequency of a magnetic platelet as a function of the applied ﬁeld. This gives a quantitative model of the inﬂuence of the applied magnetic ﬁeld on the effective Young’s Modulus of the material.
