♥ Features:- This is a real solar maglev motor model. It is made by hand and consists of 4 solar silicon wafers, copper coils, strong magnets and acrylic brackets.- Solar panels: High efficiency conversion, only need light irradiation, it will automatic rotation, the best light source is the strong sunlight.- Acrylic board is a kind of plastic. Please do not put it in the car or high temperature place, otherwise it will cause deformation of the acrylic plate and damage the product.- The rotor is suspended on the base, this design makes the friction is extremely low, suitable for high-speed rotation.- The product can be rotated in a weak light, the stronger the light, the faster the speed.- Strong magnets are fragile. Please do not allow strong magnets to absorb freely. Strong impact can damage the magnet.- Handmade DIY solar magnetic levitation generator, which will exercise the child's physical experiment ability, stimulate the child's practical ability, and improve the child's interest♥ Specification:Material: Acrylic, Magnets, Solar Panels, Copper Enameled WiresType: horizontal suspension, four-sided solar panelPrinciple: photoelectric effect, electromagnetic induction, mechanicsSize: 16*7*6.8 cmWeight : 0.5 kg♥ Package Included:1 x Solar Magnetic Levitation Model
