Electromagnetic Piston Engine Car

The electromagnetic piston engine according to the present invention in one aspect comprises a cylinder and a piston, each made of a magnetic material, a cylinder electromagnet having an inner wall of the cylinder magnetisable to a one magnetic pole, and a piston magnetization unit for magnetizing a portion of the piston engage able with the cylinder to a single magnetic pole in a fixed manner, in which the piston is transferred in a one direction by creating a magnetic attraction force between the cylinder and the piston by exciting the cylinder electromagnet; Continue reading Electromagnetic Piston Engine Car

Characterization and Modeling of the Magnetomechanical Behavior of Iron-Gallium Alloys

Abstract :-
Magnetostrictive Iron-Gallium alloys (Galfenol) demonstrate moderate magnetostriction (~350 ppm) under very low magnetic fields (~100 Oe), have very low hysteresis, high tensile strength (~500 MPa), high Curie temperature (~675°C), are in general machinable, ductile and corrosion resistant. Therefore, they hold great promise in active vibration control, actuation, stress and torque sensing in helicopters, aircrafts and automobiles.
