The strong magnetic field inside a solenoid can be used to magnetize a piece of magnetic material, like soft iron, when placed inside the coil. The resulting magnet is called an electromagnet.

The magnetic field lines inside the solenoid are in the form of parallel straight lines, indicating a uniform magnetic field at all points inside the solenoid.

One end of the solenoid behaves as a magnetic north pole, while the other end behaves as the south pole.

The pattern of magnetic field lines around a solenoid is similar to that around a bar magnet.

A solenoid is a coil of many circular turns of insulated copper wire wrapped closely in the shape of a cylinder.
