Discovery paves way for “optical battery” to generate solar power without solar cells

Discovery paves way for “optical battery” to generate solar power without solar cells: "It has long been thought that, even though light has electric and magnetic components, the effects of the magnetic field are so weak that they could effectively be ignored. Now researchers at the University of Michigan (U-M) have discovered that under the right conditions, a light field can generate magnetic effects that are 100 million times stronger than previously expected."
