According amps right-hand rule, "24V DC Cooling Fan" through the current conductor, will produce a magnetic field around, if this conductor 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. "24V DC Cooling Fan" around the silicon steel plate, two coils wound around the axis portion, and a Hall sensor component as a synchronous detection means for controlling a circuit for the two coils wound around the axis of rotation of work. Silicon have different magnetic poles, the magnetic repulsive force and the rubber magnet suction. When the "24V DC Cooling Fan" suck repulsion is greater than the static friction when lice fan, fan natural rotation. Since the Hall sensor component provides synchronization signal, the fan was able to continue to operate, as its running direction, decided to follow Fleming right-hand rule.
