Natural magnets have very small attracting power & do not have any definite shape. Hence they are not used for practical purposes. Now a days, powerful artificial magnets of iron, steel & some special alloys are manufactured. These can be made in any desired shape, e.g. , bar-magne, horse shoe-magnet, magnetic needle, etc..
