Detailed Solution

The above statement is True.
A solenoid is a coil containing several turns in which the wire is wrapped in the shape of a cylinder. It is used as an electromagnet. A solenoid is a coil of wire tied across a piston made of iron in the form of a corkscrew. According to the laws of electromagnetism, a magnetic field is generated when an electric current passes via the wire. Therefore, it is used as an electromagnet. The poles of the bar magnet are present within it, whereas for a solenoid, the poles are outside. The end of the current-carrying solenoid at which the current flows anti-clockwise behaves as a north pole, while that end at which the direction of the current clockwise behaves as a south pole, according to clockwise.
