Abstract
A magnetostrictive method and apparatus for propelling an object through a medium wherein one end of a magnetostrictive rod is firmly attached to a housing connected to the object and the other end of the rod is in contact, direct or through a flexible membrane, with the medium. Magnetic field pulses are created by energizing a coil located radially around and proximate to the magnetostrictive rod, said magnetic field pulses causing the rod to rapidly expand and contract longitudinally, in the presence and absence, respectively, of the magnetic field. A plurality of magnetostrictive rods can also be used to propel the object.
