Abstract
A mass magnifier is created by combining the properties of permanent magnets or electromagnets with the property of mu-metal to create a novel energy storage device. In a system mu-metal is placed in the magnetic field created by a magnet or electromagnetic in a manner to provide an energy storage device, similar to a fly wheel. The system includes a set of magnets arranged in a circle around a cylinder in a stationary position, effectively forming a stator. Another set of opposing magnets are arranged to form a rotor. When the rotor is rotated, mu-metal material is inserted between the rotor and stator magnets in a manner so that the rotor will remain in motion in a desired rotation direction, even if an opposing force is applied to the rotor axle. The system, thus, forms an energy storage device similar to a fly wheel. The system can also provide energy storage for conventional machines or for smaller micro-technology or nano-technology type devices.
