Minerals are one of the most commonly used materials in mechanical applications in any type of industry, and traditional metallurgy has gone too far in helping designers with a very large range of high-performance metals.

There are many different ways that make metals more powerful such as hardening by operation and alloy making, as well as hardening dispersion, etc., and it can significantly improve the properties of many metals.

By adding fairly small amounts of secondary quantities, which are usually in the form of particles, wires, and secondary pipes, we will address the subject of metals in detail in terms of the identification, types, properties, and use of metals, as well as the most important metals attracted to magnets.

What are minerals and their definition?

Minerals can be defined as a group of chemicals available on earth in their natural form, returned in the form of solids to temperatures as well as at standard pressure, and minerals with a certain chemical composition resulting in crystal-shaped atoms

Minerals are also considered to be inorganic materials and are naturally available in nature without any human intervention, such as steel made in the form of alloys as well as pearls and wood, which are also the result of the work of living organisms. These minerals are also scattered on Earth in various natural and geological environments and can also be found in lakes, volcanoes, and rocks as well as in the oceans.

Although minerals have many characteristics that shape their identity, characteristics and recipes, in nature there are some minerals that are considered abnormal in their properties from those of other base metals, such as mercury, where mercury is considered a mineral but is present in liquid conditions at room temperature..

What are the properties of minerals?

Here we explain that minerals have many characteristics that make them different, namely gloss or what is known as sparkle, and work against or absorb colors.

Also characteristic of magnetism, characterized by electrical connection and rigidity, qualitative weight and split ability.

Metal classification

We classify minerals mainly based on their physical properties, which are the composition of their crystals as well as their most important chemical properties, which are their chemical composition, into a range of key categories

First: Original metal elements

These minerals are common in terms of their similar crystal structures, i.e. they share their crystal structure, in addition, metal metals have similar physical properties such as wrought, flexibility, electrical conduction and gloss, including copper, silver, and gold metallic metals..

Second: Semi-metal

These metals are simply characterized by their crystalline composition in addition to being fragile and characterized by many properties that mediate between the properties of metal metals and metal metals, such as the ability of low-metal semi-metals to deliver both electricity and heat and such as semi-metals antimony and arsenic.

Third, non-metallic metals

It is characterized by its different characteristics and recipes entirely from metal metals such as sulfur, diamonds, and graphite, all of which possess and consist of different chemical formulations that distinguish in their different hardness, qualitative weight, and attractiveness such as oxides, hydroxides, sulfides, sulphonates, delicate, sulfates, phosphates, nitrates, hate, halides, and carbonate.

Minerals attracted by magnets

The definition of magnets is called magnets: it is considered a type of stone that is largely present, available and natural. It also features and specializes in the characteristic of the attraction of some metals and this force is called the power of magnetic attraction and the reason for that unique property is that it has been observed and discovered since ancient times.

The magnet also consists of two poles, the South Pole and the North Pole, which generate magnetic force. This natural magnetic force is also characterized by attraction and not lost to it over time, and it is possible to manufacture magnets industrially from cobalt and iron, but there are some types of magnet manufacturers these species lose their properties from the atmosphere of attraction over time.

Magnet

A material that can generate a magnetic field through which metals can be attracted, and scientists at the end of the 19th century were able to test the ability of all known elements, and most compounds to show magnetic properties.

These materials, which are attracted to magnets, are divided into two types:

Iron magnetic materials: These materials are heavily attracted to magnets so they are used to make continuous and permanent magnets, examples of ferrous magnetic materials are iron, nickel, cobalt, some rare metals such as neodymium, gadolinium samarium, and some other alloys such as alloy steel.

Magnetic materials that are in keeping: they are called paramagnets and these substances are very attracted to magnets, but they are attracted by a quantity and a ratio so small that this ratio can only be felt through a set of highly sensitive scientific equipment and these materials with magnetic prophetical molybdenum, tantalum, and magnesium.

The most important metals that are attracted to magnets

Magnets can attract some types of minerals, the most important of which are

First: Iron metal

It is located on the list of minerals that are very strongly attracted to magnets due to the unique excellence of iron atoms in many characteristics, when they are placed in a magnetic field, they are affected and begin to ensue in a complex and unique way, which becomes two poles: the North Pole and the South Pole, from different directions and therefore attracted by magnets.

·        If the magnetic field is very strong, the iron then shifts from a neutral shape to a new magnet, which is the method used to manufacture a new magnet.

Second: Steel

It is a combination of some metals and iron it is available but in the form of a certain solid slab which is also a type of metal that is attracted to magnets but less than iron.

Third: cobalt and nickel

They are also minerals that are attracted to magnets but weaker than iron.

What are the uses of magnets?

We find that magnets are available largely and naturally and can be manufactured in the form, size and magnetic field that we want and from ancient times until now the uses of magnets have multiplied in everyday life, and in many industries

The most important uses of magnets include:

·        Magnets enter into their ability to manufacture the compass that determines our directions.

·        Magnets are used in many electronic devices and computers to store data on hard disks.

·        They are also used in small speakers found in computers, TVs, and radios.

·        Magnets are also used when mines use magnetic sorting machines to separate rocks from metal ores.

·        Magnets are also used in the field of medical devices and MRI devices use many powerful fields that help them generate radio signals that give them a clear picture of the body.

·        Magnets are also used in the manufacture of speakers which become able to convert mechanical energy into electric energy and vice versa. Magnets are also used in the manufacture of the refrigerator as it helps the user to close the refrigerator door.
