Researchers at the Ohio State University have discovered how to control heat with magnetic fields, proving that both heat and sound have magnetic properties.
The study has shown that photons, the elementary particles that transmit both heat and sound, have magnetic properties. It implies that a strong magnetic field could be used to steer and control sound waves in the future.
Heat and sound are essentially the same form of energy, focused around the vibration of atoms, so by controlling one you can usually gain control of the other too.
The researchers published their report in the March 23 issue of the Nature Materials journal. It was funded by donors including the U.S. Army Research Office, the U.S. Air Force Office of Scientific Research and the National Science Foundation.by
