Photomagnetic effect

The Magnetic Effect is a quantum mechanical mechanical discovery by Samuel L. Oliveira and Stephen C. Rand at the University of Michigan 2007-2011. [1] [2] [3] [4] The Researchers Discovered-have a Powerful magnetic interaction entre les photon dynamic magnetic field – and some isolator materials Atoms magnetic moment, That Is 100 million times stronger than formerly Anticipated. Under the proper Circumstances, the photons magnetic fields effect is as strong as Their electric field – as eg in solar cells .

The discovery is a surprise, because it is not straightforward to derive the strong magnetic effect from the physical equations, and that this quantum mechanical effect would be interesting enough. That is why the photomagnetic effect has been neglected for more than 100 years.

The Researchers-have Theoretically Calculated That incoherent light as eg sunlight , is Almost as efficient as laserlight , to be converted by the photomagnetic effect.

The power density should be 10 million watt per square centimeter, but the researchers will look for new photomagnetic materials, which can work with lower light intensities .
