The magnetic field of an infinite solenoid is precisely zero outside and has a constant value inside the solenoid. The infinite solenoid is often a reasonable approximation of a real-world, finite-length solenoid if we can accept that the magnetic field will be slightly different from that of an infinite solenoid in the vicinity of the ends.

Derived from two Greek words: Solen (pipe) and Eidos (coil), the solenoid is a type of an electromagnetic device that converts electrical energy into mechanical energy. It is generally made by tightly wounding wires in a helix shape around a piece of metal. Whenever an electric current passes through it, a magnetic field is created.
Solenoids. A long wire wound in the form of a helical coil is known as a solenoid. Solenoids are commonly used in experimental research requiring magnetic fields. A solenoid is generally easy to wind, and near its center, its magnetic field is quite uniform and directly proportional to the current in the wire.
