Solar Windmill Brain Game DIY Car Decoration Technology Machinery Assembly Scientific Experiment Model

Product name: Solar windmill Voltage: 0.5V Power: 0.5W Size: 110*65mm Weight: 60g Note: Although it is a metal product, please do not drop it; it needs sunlight to rotate, which is unacceptable in rainy days; please do not move any screws easily to avoid structural instability and other damage! If you have any questions about this product, you can write to us, we will answer your questions as soon as possible!

• 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
