HOW IS IT WORK?We would love to tell you that we have discovered the ''anti-gravity formula'' but actually it is simple physics. The surprising movements of Moondrop are caused by Lenz's law which is well known in physics world. Moondrop is made from pure copper or aluminium ring, aluminium body and strong neodium magnets inside the thin aluminium tube.Copper and aluminium is a non magnetic materials however they are great conductors of electricity while each magnet is surrounded by it's own magnetic field. When the magnet moves through conductor such as sliding copper ring it's magnetic field induces an electric current in the copper. According to Lenz's law that current creates an opposite magnetic field that adds certain resistance to moving magnet. That makes the slider move slower than it would normally do if made from other materials (without electrical conductivity). Depending on proportions between magnet and conductor different sliding speed can be achieved.Moondrop Mars:The slider is made from pure copper. The distance of falling slider is 38 mm. The time for slider to fall that distance is 0,13 s which is the same as for any object dropped on the Mars and falling it's first 38 mm.Moondrop Earth:Turn any of Moondrops into Earth version by removing the magnets and compare the gravity between all three.Gravity falling objects also have acceleration therefore it is measured with m/s- that means the longer they fall the faster their falling speed is. Using Lenz's law we can not achieve that acceleration however the distance is so small that the acceleration is almost invisible with naked eye and the free-fall looks as natural as it would look on Moon and Mars.
