उत्तर
A magnet is a piece of metal that can attract metals such as iron-cobalt and nickel. Naturally occurring rocks such as Lodestone or magnetite have the ability to attract magnetic substances and hence are called natural magnets.
Magnets that are made by man from magnetic substances ara called artificial magnets. These come in different shapes such as bar magnets, horseshoe magnets, disc magnets, and ring magnets. Artificial magnets can be made in any size, shape or strength as desired but natural magnets cannot be made as desired.
