Explanation:
Hi mate!!
Bar magnets are rectangular and narrow objects that are made up of steel/iron/ferromagnetic materials which have the ability to generate a magnetic field. All bar magnets have two poles: the north pole and the south pole which are painted red and blue for identification purposes respectively.
They are usually made from iron or steel, but they can also be made from any ferromagnetic substance or composite such as cobalt, nickel, aluminum or clay. Bar magnets have a south and north pole on each end and are the most common type of magnet shape.
