Detailed Solution

The above statement is True.
A magnet is an object capable of attracting unlike poles and repelling like poles.
Magnets are of two types, natural magnets and artificial magnets.
       Natural magnets occur in nature, and they are permanent and will never lose their magnetic power.
       Humans make artificial magnets, and they are made extra strong. Artificial magnets have two types of magnets: temporary and permanent. Artificial magnets have different shapes, such as bar magnets, horseshoe magnets, and cylindrical magnets.
Magnetism is a property of a material which does not depend upon the shape and size of the magnetic object, and they can be of any shape and size. The strength of a magnet is not affected by its shape. However, if a magnet has an additional pointed end, that end will be stronger than the other magnets. This is because the shape affects the supply of magnetic energy in the space it occupies.
