Magnetism is the phenomenon of attraction or repulsion observed between certain bodies, called magnets, between magnets and certain magnetic substances (such as iron, cobalt or nickel) and also between magnets and conductors that are conducting electrical currents. Every magnet has two distinct regions, in which the magnetic influence manifests itself with greater intensity. These regions are called magnet poles. These poles have different behaviors in the presence of other magnets, and are called North (N) and South (S). One has the impression that the poles of the magnet are identical, but this is not true, since by suspending the magnet horizontally by a thread tied to its center, it appears that, after a series of oscillations, it always returns at the same end substantially to the north and the other to the south. For this reason, the north pole is called the end that faces north, and the south pole the other.

We call TEMPORARY MAGNET that one that behaves like a magnet only when in contact or in the vicinity of another magnet. Based on your knowledge of the behavior of magnets, explain when a magnet can lose its magnetization.
