Magnetic momentum transfer generator
A magnetic momentum transfer generator utilizes three or more magnets aligned with each other. A first control magnet is positioned outside a coil. A second magnet is positioned within the windings of the coil and a third magnet is positioned on the opposite side of the coil opposite the control magnet. When the control magnet rotated or moved, mutual magnetic flux lines generated by all three magnets and passing through the coil winding are aligned at right angles to the coil, thereby inducing a maximum voltage at the terminals. This generator is particularly useful for short burst radio micro-transmitters that can be used for battery-less and wireless switching applications.
