Solenoid is a cylindrical coil of wire which act as a magnet when carrying current.

A coil of circular insulated copper wire wrapped closely in shape of a cylinder is called a solinoid

a cylindrical coil of wire acting as a magnet when carrying electric current
A solenoid is a coil of insulated or enameled wire wound on a rod-shaped form made of solid iron, solid steel, or powdered iron. Devices of this kind can be used as electromagnets, as inductors in electronic circuits, and as miniature wireless receiving antennas
