The Ohio State University has released details about a project with magnets its researchers have been working on. According to their work, magnets are able control both heat and sound waves -- something recently detailed in the journal Nature Materials, and the first time such information has been proven. Said one of the researchers, this experiment has added "a new dimension to our understanding of acoustic waves", and that using magnets researchers are able to "steer" both heat and sound waves.

In the experiment recently detailed, the researchers are said to have decreased the heat in a semiconductor by 12-percent using a magnetic field about the size of what you'd get from a medical MRI. In doing so, the researchers were the first to prove that acoustic phonons are magnetic to some degree...
