ABSTRACT:
A rotary magnet device comprises at least two circular arrays of wedge-shaped magnetized elements which are angularly adjustable about their respective radial axes. The elements of each array are arranged in surface-to-surface facing relationship with surfaces of one polarity facing surfaces of opposite polarity, thereby creating a magnetic field about a respective array. Rotary motion is created when the magnetic fields of the respective arrays are brought together to interact. The rate and direction of and torque created by rotation can be selectively varied by angularly adjusting the magnetized elements relative to their radial axes.
