  • Magnetostriction is a property of  ferromagnetic materials such as iron, nickel, and cobalt. When placed in a  magnetic field, these materials change size and/or shape.
  • An important characteristic of a wire  made of a magnetostrictive material is the Wiedemann effect. When an axial  magnetic field is applied to a magnetostrictive wire, and a current is passed  through the wire, a twisting occurs at the location of the axial magnetic  field. The twisting is caused by interaction of the axial magnetic field,  usually from a permanent magnet, with the magnetic field along the  magnetostrictive wire, which is present due to the current in the wire.
  • The current is applied as a  short-duration pulse, -1 or 2 µs; the minimum current density is along the  center of the wire and the maximum at the wire surface. This is due to the  skin effect.
  • The magnetic field intensity is also  greatest at the wire surface. This aids in developing the waveguide twist. Since  the current is applied as a pulse, the mechanical twisting travels in the  wire as an ultrasonic wave. The magnetostrictive wire is therefore called the  waveguide.
