    • An apparatus for inducing drive is shown that includes a primary drive shaft and four secondary drive shafts. The primary shaft and secondary shafts are fitted with magnets that are oriented such that when the primary shaft is rotated the secondary shafts are caused to rotate due to attractive or repulsive forces. The primary shaft is connected to and rotated by a rotational energy source such as a motor powered by electricity or a battery, although any source of energy to cause rotation of the primary shaft may be used. Each secondary shaft is fitted with two annular magnetic discs that are oriented to vertically support the weight of the shaft (and any attachments/fittings thereto) above the alternating or generating device. The discs can be arranged to provide either an attractive or repulsive magnetic force between them.
