We have a rough idea of the size and shape of this field, but the fine particulars elude our understanding. Now, a new computational study has revealed a surprising structure – a spiral generated by ...

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.
