Researchers at the University of Michigan have discovered a new property of light that allows them to harness the magnetic attributes of light. Electromagnetism being a classically unified force, the relationship between light and magnetism is well known, but the magnetic component was thought to be weak enough that it could be safely ignored. Stephen Rand, a professor at UMich, said of this, "You could stare at the equations of motion all day and you will not see this possibility. We've all been taught that this doesn't happen. It's a very odd interaction. That's why it's been overlooked for more than 100 years." Scientists are so awesome.
