很多人都用过电磁炉,它利用磁场,能以无线的方式给锅加热。最近日本科学家研制出一种电磁无线输电器,能够无线传输电力,用它供电的电器就再也用不着电线和插头了。这种“无线”输电器里面装有感应元件,当它感应到附近存在电力接收器时,就可以在特定区域提供无线电能。电网的电力被它转换成磁场后,被电器再经过一次转换变成电力。空中传输的电力没有漏电的危险,如同电磁炉一样用手摸它也不会被电击或烫伤。它体积小巧重量只有50克,可以放在地板下、镶在墙里、天花板以及所需要的任何地方,甚至水中也可以使用。但只有配备了
Many people have used the induction cooker, which uses the magnetic field to heat the pan wirelessly. Recently, Japanese scientists developed an electromagnetic wireless power transmitter that can wirelessly transmit power and use it to power no more wires and plugs. This “wireless ” transmitter has a sensing element inside it, which provides wireless power in a specific area when it senses the presence of a power receiver nearby. After the power of the grid is converted into a magnetic field by it, it is transformed into electricity by the electrical appliance once again. There is no danger of electric leakage in the air, so it will not be shocked or scalded like a cooker. It is compact and weighs only 50 grams, can be placed under the floor, set in the wall, the ceiling and wherever it is needed, and even water can also be used. But only equipped
