Anonim

It is a body whose magnetic field acts in conjunction with other elements, as a means of attracting other bodies, especially metals. Today, it is one of the most common items, so it can not only be found in its natural form, it is also synthesized; This has begun to be practiced to market the product much more quickly. The magnet can lose its magnetic field if it is subjected to heat, a fact that the ancient Greeks knew, which is why they gave it the name of "adamantos" (diamond), expressing "a" a kind of disappointment and "damao" (transformed damantos) issues related to fire.

The most powerful magnets are natural ones, also known as magnetite, their magnetic field being constant and resistant to the passage of time. Most of what it attracts are pieces of iron, as well as other magnetic substances. Artificial ones, on the other hand, do not have the characteristics of a common magnet naturally, so through chemical processes it is delegated the power to attract objects. However, they can also be called permanent or temporary, the former being those that have the properties of a natural magnet throughout its useful life because they are manufactured with special components, and the latter being a body that has a controlled lifetime.

The force of the magnets intensifies at their ends or poles, repelled or attracted depending on whether they are the same or different, respectively. This element is present in many regular products, such as credit card bands, hard drives, coded keys, horns, compasses, among others.
