Kore is a very efficient motor/generator system. Permanent magnets in a circular wheel array are attracted to the non-magnetized metal core of secured electromagnets. When the permanent magnets are approximately centered on the electromagnets, a pulse of current is applied to the electromagnets, releasing the magnetic grip.
The energy needed to create enough force in the electromagnet to release the magnetic grip of the permanent magnet is less than the force of the attraction of the permanent magnet to the non-energized metal core of the electromagnet.
Coils are positioned around the circumference of the rotating permanent magnets to create a current.
In 1821, Michael Faraday demonstrated the conversion of electromagnetic force into mechanical energy. In 1832, William Sturgeon invented a commuter-type direct current motor that had practical application. In 1837, Thomas Davenport invented a motor that had the first commercial application. These motors were too expensive to have a market commercially. In 1873, Zenobe Gramme accidentally invented a motor that had commercial success. In 1888 Nikola Tesla the first usable AC motor.
A generator is a device that converts mechanical energy into electrical energy. The first generators used electrostatic induction to produce electricity. Examples are the Wimshurst machine and Van de Graaff generator.

The energy needed to create enough force in the electromagnet to release the magnetic grip of the permanent magnet is less than the force of the attraction of the permanent magnet to the non-energized metal core of the electromagnet. Creating a coil wrapped around the circumference of the permenant magnets causes a significant current.
