Find the principle of Mendocino motor

First of all, we must understand from the Mendocino rotor structure that it will continue to rotate even without magnetic levitation. Domencino is a solar panel that generates a magnetic field for the coil when exposed to light. After turning a certain angle, the power weakens and the magnetism disappears, and the solar panel on the other side continues to generate electricity to generate a magnetic field. It will continue to rotate due to inertia. The four-piece Domencino consists of two opposing solar cells connected in series to power a set of coils. After turning 90 degrees, the power is cut off and the solar cell on the other side provides kinetic energy to continue cutting the magnetic field lines. Assume that A1A2 is the opposite surface and B1B2 is the opposite surface. The illumination A1 causes the coil to generate a magnetic field and rotates 90 degrees. The illumination offset (the power weakens) is caused by B1 being illuminated and continuing to rotate 90 degrees. By analogy, the illumination in the opposite direction will rotate in the opposite direction, because The lighting sequence changes. I wonder if everyone can understand it? If it does not rotate, it may be that the direction of the coil is wrong. Just reverse the polarity of one of the coils to change the direction of the magnetic field.
