Is the magnet made of steel or iron Why is it smack

Magnets are made of iron.

Because of the nature of the magnet.

Iron is said to have two lattice structures, gamma iron with a face-centered cubic lattice structure at temperatures above 727 degrees Celsius, and alpha iron at temperatures below 727 degrees Celsius.

Alpha iron of a body-centered cubic lattice is ferromagnetic.

Gamma iron with a face-centered cubic lattice structure loses ferromagnetism above 770 degrees (Curie point).

Some steels, especially stainless steels, are made to maintain the austenitic structure of the face-centered cubic lattice structure at room temperature by adding alloying elements, so they are not ferromagnetic.

There are many kinds of magnets, commonly used are: samarium cobalt magnets, NdFeB magnets, Alnico magnets, ferrites, plastic magnets, etc.; These magnets can be seen from the name, and they are roughly composed of metallic elements. Of course, some other elements are added to it in order to achieve a specific performance.

The manufacturing process is sintering, bonding, casting, etc. The performance of each type of magnet is different, and the environment in which it is used is also different. According to the specific type of magnet you need, check the information or call ** to the manufacturer for consultation.

Magnets, should be called magnets, English magnets, magnets are now mainly divided into two categories, one is soft magnetic, the other is hard magnetic;

Soft magnets include silicon steel sheets and soft magnet cores; Hard magnets include Alnico magnets, samarium cobalt, ferrite and NdFeB, among them, the most expensive is samarium cobalt magnets, the cheapest is ferrite magnets, and the highest performance is NdFeB magnets, but the most stable performance and the best temperature coefficient are Alnico magnets, and users can choose different hard magnetic products according to different needs.

Steel is a mixture that contains a certain amount of carbon, while a magnet refers to an object or material that can generate a magnetic field, usually made of a metal alloy that is highly magnetic. Traditionally, they can be divided into "permanent magnets" and "non-permanent magnets".

Copper and aluminum without a primary magnet structure cannot be attracted to magnets.

The magnet is pressed with ferric tetroxide powder foam plus filler and binder.

Its composition is iron, cobalt, nickel and other atoms, the internal structure of the atom is relatively special, and it itself has a magnetic moment.

The magnetic strength of magnetite has a certain relationship with the content of ferric tetroxide, the more ferric oxide content, the stronger the magnetism of magnetite, on the contrary, the less the content of ferric tetroxide, the weaker the magnetism.

Application of magnets in traditional industries:

When talking about the magnetism**, electromagnetic induction, and magnetic devices of magnetic materials, we have already mentioned the practical applications of some magnetic materials. In fact, magnetic materials have been widely used in various aspects of traditional industries.

For example, without magnetic materials, electrification would not be possible because generators are used to generate electricity, transformers are used to transmit electricity, electric motors are used in electrical machinery, and loudspeakers are used in electric machines, radios, and televisions. Many instruments and meters use magnetic coil structure.

The main raw materials of magnets are rare earth metal neodymium, rare earth metal praseodymium, pure iron, aluminum, boron-iron alloy and other rare earth raw materials. Magnets, also known as magnets, are capable of generating magnetic fields that can attract ferromagnetic materials such as iron, nickel, cobalt, and other metals.

Magnets can be divided into permanent magnets, non-permanent magnets, permanent magnets are natural magnets, or they can be artificially manufactured, and non-permanent magnets need to be magnetic under certain conditions.

The first to discover and use magnets should be the Chinese, that is, the use of magnets to invent the compass, the compass is one of the four great inventions of ancient China.

Magnets have a wide range of applications and can be used in traditional industry, medicine, astronomy, military and other fields.

The natural magnet is ferric tetroxide.

Whereas, artificial magnets are usually steel.

Steel retains its magnetism after it has been magnetized.

The general natural permanent magnet is not only ferrite (ferric oxide), but also iron, cobalt-nickel alloy, iron rare earth alloy and other permanent magnet materials, such as alniccot, samarium cobalt, neodymium iron boron, these are also very common, very magnetic, these substances can be magnetized by the magnetic field constant magnetic field, and magnetization itself is magnetic and does not disappear.

The composition of artificial magnets depends on the magnetization properties of various metals.

Magnets, known as natural magnets, are still one of the most important magnets due to their excellent adaptability to high temperatures. Alnico can work normally at high temperatures above 500 °C, which is the biggest feature, and the corrosion resistance is also stronger than other magnets.

Its metal composition is different, the magnetic properties are different, and thus the use is also different, mainly used in various sensors, instruments, electronics, electromechanical, medical, teaching, automobile, aviation, military technology and other fields. Alnico magnets are one of the oldest magnets, known as natural magnets, and although they are the oldest, their excellent adaptability to high temperatures makes them still one of the most important magnets. Alnico can work normally at high temperatures above 500 °C, which is its biggest feature, and its corrosion resistance is also stronger than other magnets.
