University of Michigan boffins have discovered, while shooting lasers through glass, that light shining through non conductive materials exhibit strong magnetic characteristics.
The magnetic properties of light were thought to be so weak that they could simply be ignored. With this research that has all changed, the assumption as it turns out was drastically wrong. They discovered that extremely powerful light can generate magnetic fields 100 million times stronger than previously estimated. “Strong enough to induce useable voltages and create magnetic batteries.” Professor Stephen Rand says, adding, “Enough sunlight, focused into an optical fiber, could generate electricity – that’s is a simple way to think about it.”
