Abstract
Abstract An electric motor which uses electric current to produce a magnetic field emitted from electromagnet(s) 5 and 6, resulting in the motion of a permanent magnet(s), serving as piston(s) 9 and 10; this by the interaction of their magnetic fields. The motion of the piston(s) shall result in the inversion of electricity due to the piston(s) passage through induction coils 11 and 12. The invention may serve many purposes including, but not limited to, a power plant for a means of mechanical locomotion, the driving force necessary for machinery, gadgetry, or hydraulic equipment.
