How a works, and its how an electric toothbrush recharges. It takes three basic steps: Current from the wall outlet flows through a coil inside the charger, creating a magnetic field. In a transformer, this coil is called the primary winding. When you place your toothbrush in the charger, the magnetic field induces a current in another coil, or secondary winding, which connects to the battery. This current recharges the battery. You can use the same principle to recharge several devices at once. For example, the Splashpower recharging mat and Edison Electric's Powerdesk both use coils to create a magnetic field. Electronic devices use corresponding built-in or plug-in receivers to recharge while resting on the mat. These receivers contain compatible coils and the circuitry necessary to deliver electricity to devices' batteries. Eliminating the power cord would make today’s ubiquitous portable electronics truly wireless. Conclusion From these researches and discoveries it can be said that wireless power transmission is going to be a major field of interest for scientists and for people. The facts that the power can be transmitted from space to earth will revolutionize the field of satellites. Since the uses of wireless power transmission are many, from easy installation, neatness, easy maintenance to multi-equipment working are amazing, thearea for researchers on this field seems very interesting. Rather concentrating on the false beliefs, the concentration should be put on advantages of witricity for further increasing the efficiency of wireless power transmission with more safety measures. It is a rocking technology provided the researches continue to move in same speeding direction.
