♥ Features:- This is a real solar maglev motor model. It is handmade and consists of four silicon solar wafers, copper coils, strong magnets and acrylic mounts.- Solar panels: high efficiency conversion, only need light irradiation, it automatic rotation, the best light source is strong sunlight.- acrylic board is a type of plastic. Please don't 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 weak light, the more light, the faster the speed.- strong magnets are fragile. Please do not allow strong magnets to absorb freely. strong impact can damage the magnet.- DIY hand solar magnetic levitation generator, which will exercise the child's physical experience ability, stimulate the child's hands-on ability, and improve the child's interest♥ Specification:Material: acrylic, magnets, solar panels, enameled copper wiresType: horizontal hanging, four-sided solar panelPrinciple: the photoelectric effect, electromagnetic induction, mechanicsSize: 16*7*6.8cmWeight: 0.5kg♥ The package contains:1 x Solar Magnetic Levitation Model
