All magnets, regardless of their shape or application, have two poles, the north pole (N) and the south pole (S), which are called magnetic poles.
Today, there is a wide variety of magnets. They appear in the most varied forms and are used from decorations for refrigerators to technological application.
Properties of the Magnets
1 . All magnets, regardless of their shape or application, have two poles, the north pole (N) and the south pole (S), which are called magnetic poles.
2 . As with electrical charges, it is observed in the behavior of magnets that poles of the same name repel each other and poles of opposite names attract.
3. Another important characteristic of magnets is the inseparability of the magnetic poles, that is, it is not possible to find a magnet with only a north pole or only a south pole. Thus, when a magnet is broken, it will give rise to two new magnets and the polarity of these new magnets will depend on the way in which they were partitioned.
If a magnet moves freely, one of its poles will align with the Earth’s geographic north pole, this is the magnet’s north pole, and the other pole will align with the geographic south pole, thus being called the magnet’s south pole. This is why the poles are called the North Pole or the South Pole.
