★This product uses solar power to supply electricity to the coil wound on the shaft to generate a magnetic field. It generates a repulsive force with the strong magnet fixed on the base (housing) to push the rotation. Because of its unique magnetic suspension structure, there is almost no friction, and it has high speed, quietness and durability.
★The internal structure is completely exposed, which provides convenience for teaching demonstrations and is highly enjoyable.
★Different angles of sunlight can generate magnetic fields in different directions to achieve forward and reverse rotation.
★Made of metal, strong and durable, polysilicon solar panel, high utilization rate
★It is very suitable as a gift to children or students, which can effectively improve children's interest in learning
