It is shown here that two permanent magnets with opposite poles facing can attract along their equatorial plane and then repel along their polar plane in sequence, without reversing polarity and without the use of another source of energy. This sequence of attract and repel between two permanent magnets is like the attract and repel sequence between an electromagnet and permanent magnet in an electric motor. The discovery described here can be used to construct a motor driven entirely by permanent magnets.展开更多
