Abstract:
A method for reducing a temperature rise of a magnetic material is provided. The method includes applying force to the magnetic material to reduce a dimensional change of the magnetic material during a first part of an operation cycle, such as due to magnetostriction. The force is removed from the magnetic material during a second part of an operation cycle, allowing magnetostrictive dimensional changes to occur.
