Abstract
The present invention eliminates vibration of an electromagnetic device, apparatus or machine caused by magnetostrictive and Joule effects. Specifically, the present invention discloses making an electromagnetic device, apparatus or machine with magnetostrictive contracting and magnetostrictive expanding materials. Once exposed to a magnetic field, the amount of contraction and expansion of the materials should be virtually the same to minimize generation of vibratory energy that can be transmitted from a core to a housing.
