Inductance of a solenoid

Description

A solenoid is a coil wound into a tightly packed helix. In physics, the term refers specifically to a long, thin loop of wire, often wrapped around a metallic core, which produces a uniform magnetic field in a volume of space (where some experiment might be carried out) when an electric current is passed through it. Inductance is the property of a conductor by which a change in current flowing through it “induces” (creates) a voltage (electromotive force) in both the conductor itself (self-inductance) and in any nearby conductors (mutual inductance). The inductance of a solenoid is depended on the length of the coil, the cross-section area and the number of turns.
