Magnets are objects characterized by poles and the generation of a magnetic field, which is a direct result of the electron configuration within the material. Among naturally magnetic metals, we find iron, nickel, and cobalt. The unique electron arrangement in these metals allows for the creation of magnetic fields that emanate from them. It's the interplay of these magnetic fields and the poles within a magnet that governs their attractive and repulsive properties. When opposite poles are brought into proximity, they exhibit an attractive force, while similar poles, when in close proximity, will repel each other.

Despite the common term "permanent magnet," there's nothing truly permanent about their magnetic fields. All magnets possess the potential to be demagnetized, and various methods exist for accomplishing this. In contrast, temporary magnets exhibit magnetic properties, but they do not retain their magnetic field strength as effectively. Objects in this category include items like paper clips, scissors, refrigerators, staples, and numerous other everyday items. Temporary magnets are much more susceptible to losing their magnetic properties when compared to permanent magnets.

The process of demagnetizing a permanent magnet can be achieved through a variety of techniques. One such method involves raising the temperature of the magnet. Another effective means to diminish a magnet's magnetic field involves subjecting it to physical force or impact.
