Abstract
An apparatus and a method for transmitting power using magnetic force. The apparatus comprises a driving rotary element rotated by a driving motor; and at least one driven rotary element brought into contact with the driving rotary element by an attractive force and rotated in an opposite direction relative to the driving rotary element by rotation of the driving rotary element. Each of the driving or driven rotary element comprises a double-sided bipolar disc shaped magnet or a disc-shaped ferromagnetic. A pair of double-sided bipolar disc-shaped magnets can be coupled to each other with a gear interposed therebetween. A rotary decoration can be coupled to an end of the driving rotary element or the driven rotary element. A small-sized power generator having light emitting diodes can be installed on a rotation shaft which is connected to the driving or driven rotary element.
