According to Ampere right-hand rule, "24V DC Cooling Fan" by current creates a magnetic field around, if this conductor is placed in another fixed magnetic field, will produce suction or repulsion, causing the object to move. DC fan blades inside, attached to a pre-filled with rubber magnet magnetism of. Surrounded by silicon, axial part of the winding two coils, and a Hall sensor component as synchronous detection means for controlling a set of circuits, "24V DC Cooling Fan" circuit to make two sets of coils wound around the axis of rotation of the work. Silicon have different magnetic poles, the magnetic repulsive force and the rubber magnet suction. When the suction fan repulsion of static friction is greater than the lice, natural rotation of the blades. Since the Hall sensor assembly provides a synchronization signal, "24V DC Cooling Fan" fan was able to continue to operate, as its running direction, to follow Fleming right-hand rule decision.
