According to the U.S. network reported Science Daily, University of Miami and University of Tokyo and Tohoku University scientists have developed a "spin" the battery, only about the diameter of our hair so thick, it can be called by the magnetic field to the "magnetic tunnel junction (MTJ) "device to charge the magnets. The magnet is that some 5 nm thick composed of zinc gallium and arsenic magnet matrix.
This technology is expected to produce the computer hard drive does not move, than the existing hard drive will be faster, cheaper and more energy. In the future, this battery will be used to drive the car. The study, published in the March 12 issue of "Nature" magazine.
These scientists developed the device can store energy in the magnet, rather than through chemical reaction to produce energy. Stewart E. Barnes of the University of Miami, said physicist, like the toy car on the winding, as the rotating magnetic field to the battery through the winding, there is no chemical reaction. This device is any device than is currently found to be good. "We have predicted the effect, but do not know the size of this effect and duration of how long an estimated ten minutes on this unit needs to generate enough voltage, rather than what we expect of milliseconds."
