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.
