It is a common grade school experiment to wind some wire around a screw ... The coil is fed with AC. The magnetic field from the coil induces an opposite field in the copper ring that is out ...
A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet.
