The secret of unmagnetized magnets
EPFL physicists studying magnetic materials have discovered that they have some unexpected properties. Their research could lead to the development of even tinier magnets in the future.
Physicists at University of Utah developed an inexpensive, highly accurate magnetic field sensor. This new magnetic field sensor, good for scientific or consumer uses is based on “spinotronic” organic thin film semiconductor which basically is a plastic paint resistent at heat and degradation. This plastic paint is only about 5 by 5 mm (one fifth [...]

Cell phones and flashlights operate by battery without trouble. Yet because of the limited lifespan, battery power is not a feasible option for many applications in the fi elds of medicine or test engineering, such as implants or probes. Researchers have now developed a process that supplies these systems with power and without the power [...]

A Stanford University research team has designed a high-efficiency charging system that uses magnetic fields to wirelessly transmit large electric currents between metal coils placed several feet apart. The long-term goal of the research is to develop an all-electric highway that wirelessly charges cars and trucks as they cruise down the road.

The heat which occurs in tiny computer processors might soon be no longer useless or even a problem. On the contrary: It could be used to switch these processors more easily or to store data more efficiently!
