TESTS have been made recently on a superconducting solenoid constructed from what is believed to be the longest continuous length of niobium–zirconium alloy wire so far produced in the United ...

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.

A solenoid engine is a curiosity of the electrical ... The lathe was used to make the plastic spool to hold the wire, and also to help wind the wire onto the spool itself rather than doing it ...
