  • Patent number: 11515082
    Abstract: The present invention is directed to a method for producing induced electricity which prevents a collision by guiding induced electromagnetic force generated from a power generation coil as electricity is produced in the power generation coil to a predetermined location deviating from the path of power generation magnetic force which proceeds to be interlinked with the power generation coil to thus prevent power generation resistance from occurring and also produces electricity by interlinking the induced electromagnetic force with the power generation coil. The present invention is also directed to a “method for producing electricity using the induced electromagnetic force of a power generation coil” which uses an energy source for the production of electricity without conversion, so that there are no loss of energy during an energy conversion process and maintenance and management are easy, thereby reducing costs.
