Dc monopole motor with low voltage and high current is widely used in the market. It has the advantages of high efficiency, no commutator, no iron loss and so on. In this paper, an assembly (a cylindrical battery with button-type magnets attached at both ends) is placed on aluminum foil. The phenomenon that the assembly will move based on the principle of a single motor is explained. By adjusting the specifications of the button magnets and other parameters, a variety of its movement modes are theoretically analyzed and experimentally verified. The conclusion is that when the magnets at both ends are placed at the same level relative to each other and the diameter is the same, the composite body moves in a straight line with first acceleration and then uniform speed. When the diameter is different, the circular motion is accelerated first and then uniform. Changing the magnetic property size, battery length and other parameters will affect the change of motion parameters. This provides a new idea for further innovation of monopole motor in the future.
