Meaning of Magnet
What is Magnet:
A blackish, opaque iron ore is known as a magnet, which has the property of attracting iron, steel and other bodies to a lesser extent. The word magnet is of French origin "Aimant".
The magnet is a material that has the ability to produce an external magnetic field and attract iron, and others such as cobalt, nickel, aluminum, etc., but also to repel other magnetic bodies.
In view of its function, in the interior of matter there are small closed currents depending on the electrons that the atoms contain, and each one of them forms a small magnet. In this sense, the magnets must be aligned to act as a single magnet, and in this way to be able to magnetize or magnetize the substance, since otherwise it does not produce effects.
For more information, see the Atom article.
In the year 1820, it was the Danish physicist and chemist Oersted who first evidenced the process identified above, that is, that an electric current generates a magnetic field around it.
In relation to the above, a magnet can lose its magnetization property by reversing the direction of the current, or through the application of high temperatures. In this sense, every magnet is made up of the following parts:
- Magnetic axis, a bar that joins the two poles.
- Neutral line, located on the surface of the bar that separates the two polarized zones.
- Poles, ends of the magnet where the greatest attractive force is located. These poles are: the north and south. Like poles repel and different poles attract.
Magnets can be used in the industrial sector as magnetic sweepers, classifiers and separators for impure metals. For its part, in the electronics area, magnets are used in telephones, televisions, computers, radios, and speakers.
On the other hand, magnetic separation is a process that serves to separate two solids, in which one of the two must have magnetic properties or be ferrous. As such, it consists of bringing the magnet closer to the mixture to create a magnetic field, thus attracting the ferrous matter and leaving the non-ferrous material.
Magnetism is the science of physics that is dedicated to the study of magnets and their properties.
By extension, figuratively speaking, the magnet is the grace that attracts the will or attention. For example: household appliances are a magnet for children and adults.
In the religious sense, the imam -also known imam-, is the person who leads the collective prayer in Islam. The person stands in front of the other faithful in mosques as a religious, spiritual guide to perform Muslim prayer.
In English, the term magnet is "Magnet".
Natural and artificial magnet
The natural magnet refers to natural minerals that have the characteristic of attracting elements such as iron, nickel, among others. For example: magnetite, a mineral composed of ferric ferrous oxide that has the peculiarity of attracting fragments of natural iron.
For its part, the artificial magnet is a body of ferromagnetic material that, after friction with magnetite, possesses the property of magnetism.
Temporary and permanent magnet
The temporary magnet, known as an electromagnet, made up of soft iron that is characterized by having a magnetic attraction, which ceases its properties once the cause that causes the magnetism ends. On the other hand, the permanent magnet is one that is made of steel, and retains its magnetic property for a long time.
