Sound Waves Converted To Electromagnetic Energy

September 20, 2011 Leave a comment Go to comments

“Professor Eiji Saito at Tohoku University, together with researchers from JAERI and Technical University of Kaiserslautern, has succeeded in obtaining a flow of magnetism from sound waves. Such a flow is called a spin current, where spin is the angular momentum of electrons.

In this experiment, electrical signals generated at electrodes were measured, with high precision, while sound waves were input directly to the interface between a thin metal layer and a magnetic material.

This research has shown that it’s possible to obtain electrical and magnetic energy from materials of all kinds, whether they’re metals, insulators, magnetic, or non-magnetic.”
