magnets are also used in electrical bell.All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.Magnets are important because of their properties A particle moving in a magnetic field feels a force proportional to his speed, and to the field, so you can use a magnet that produce a field in a certain way and shape, in order to catch a particle in motion.
