Description

Direct current going through a coil generates a magnetic field in an iron insert. This magnetic field induces a current in an aluminium ring also sitting on the iron insert. The force acting on the ring within the magnetic field is strong enough to shoot the ring upwards. Some may use this effect for weapons – we say: For Science!
