How do Magnets work?

The north pole of one magnet attracts the south pole of another magnet, while the north pole of one magnet repels the other magnet's North Pole.  A magnet creates an invisible area of magnetism all around it called a magnetic field. Every magnet has both a North and a South Pole. When you place the North Pole of one magnet near the South Pole of another magnet, they are attracted to one another. When you place like poles of two magnets near each other they will repel each other. "Like poles repel, unlike poles attract".

Magnets don't mind the cold, some magnets perform better when the temperature drops. That's because the atoms that comprise magnets vibrate more slowly and less randomly when cold. The result is a better alignment of the atoms that generates the magnetic field, boosting its strength. It is also possible for a permanent magnet to lose its magnetism. It happens by demagnetizing magnetic field: permanent magnets exhibit a characteristic called co-ercivity, which is the ability of a material to withstand being demagnetized by an applied magnetic field.

If the two poles are the same, the two magnets will push away, or repel, from each other. This is called magnetism. Magnets can make some other metals into magnets when they are rubbed together. A magnet's magnetism decreases when it is heated and increases when it is cooled. If you can find a very strong magnet, repeatedly rub it across your weakened magnet. Magnet stacking is one way to make weak magnets stronger is by stacking more of them together.
