Why is it that only iron is attracted to magnets, but not other metals?

Any material that satisfies the magnetic condition is calledFerromagnetismIron is the most common ferromagnetic element, and the other two ferromagnetic elements are nickel and cobalt. Other metals do not meet the magnetic condition and therefore cannot be attracted to magnets. However, several other substances can also be ferromagnetic when heated or combined with other materials.

The science behind magnetism, like electricity, can be boiled down to electrons, i.e. aroundNucleusof negatively charged particles. All electrons are magnetic, just like they have electrical properties. When an electron exhibits magnetism, it has the ability to interact with an external magnetic field, so it has a magnetic moment.

Although a single atom in any substance can have a magnetic moment, it does not mean that the substance itself is magnetic. In order for the substance to be magnetic, the atoms that make up the substance need to meet two principles. <>

Matter is insideFree electrons, free electrons move between different atoms and are usually the cause of magnetism as they have a magnetic moment. In many matter, all the electrons are arranged in orderly pairs, they are bound to each other and difficult to move, each canceling out the magnetism of the other. If you imagine 1,000 trains, half of which are trying to go north and the other half south, none of them will move and therefore they will not be magnetic.

However, this alone is not enough to make a substance magnetic. Just because the electrons of a material are not arranged in pairs, does not necessarily mean that the substance is magnetic. For example, manganese is an important mineral found in nuts and grains that is essential for healthy bones, and although its electrons are not arranged in pairs, it is not magnetic.

If you have 1001 train engines, 500 of which are facing south and 501 are facing north, the extra engines don't make much of a difference. The second principle is to align enough electrons parallel to each other (as many locomotives face in the same direction) so that they are capable enough to interact with an external magnetic field to move the entire object.

Metals all have a magnetic field, and generally metals have a paramagnetic field, and there is only a slight gravitational pull on iron, and metals with an inverse magnetic field will be repelled by iron. Magnets, which have a ferromagnetic field, are strongly attracted to iron.

Because iron is particularly magnetic. Magnets exert force on all matter, but only the magnetism of iron can be attracted.

Because the minerals contained in iron are not the same as the substances in the metal skin, isn't it as the saying goes, magnets magnets have words to attract iron! So metal can't.

Magnetic fields exert forces on various metal pairs, with no exceptions. But there are three scenarios. In this way, metals are divided into three types: paramagnets, countermagnets, and ferromagnets.

1.Paramagnets: Can be slightly attracted to magnets.

2.Countermagnet: Slightly repelled by the magnet.

3.Ferromagnets: Magnets are strongly attracted.

There are only three types of ferromagnets: iron, cobalt, and nickel. The rest are either paramagnets or countermagnets. There are also their alloys, whose magnetic properties are close to ferromagnets in varying degrees.

Stainless steel containing nickel can be (strongly) attracted to magnets. Stainless steels that do not contain nickel (often containing chromium) react weakly to this iron and are not easily noticed. The latter is harder because it contains chromium. The former is commonly known as stainless iron.

Aluminum and copper are suspended in long, thin wires and made to stand still without oscillation. Slowly approach aluminum or copper laterally with a magnet and you will find that they will be slightly attracted or repulsed. So they are paramagnets and inverse magnets, respectively.

Magnets can attract iron, not steel Reason:

1. The property of magnets to attract iron, cobalt, nickel and other substances is called magnetism. The area where the magnet is magnetically strong at both ends is called the magnetic pole, with one end being the north pole (n pole) and the other end being the south pole (s pole). Experiments have shown that the magnetic poles of the same sex repel each other, and the magnetic poles of the opposite sex attract each other.

2. There are many original magnets with two opposite poles in iron, and when there is no external magnetic field, these original magnets are arranged disorderly, and their magnetism cancels each other out, and they do not show magnetism to the outside world. When the iron is brought close to the magnet, these protomagnets are neatly arranged under the action of the magnet, so that the end close to the magnet has a polarity opposite to the polarity of the magnet and attracts each other. This shows that the iron can be magnetized by the magnet due to the presence of the original magnet.

3. After some steels (especially stainless steel) are added with alloying elements, they still maintain the austenitic structure of the face-centered cubic lattice structure at room temperature, so there is no ferromagnetism.

Stainless steel will also attract magnets. The steel business has been in contact for a few years. physical properties. Don't "hear", verify it yourself. There are too many "heard" things in this society that are unfounded and not supported by scientific theories.

It is proved that the electrons outside the iron can attract each other to the external magnetic field, and the electrons inside the steel crystal just form a closed-loop loop with the magnetic field of the compound inside, and the magnetic force displayed externally is weak, which we also call inverse magnetism.

There are many polar polar magnets with two opposite magnetic poles in iron, and when there is no external magnetic field, these primary magnets are arranged disorderly, and their geomagnetism cancels each other out and does not show magnetism to the outside. When the iron is brought close to the magnet, these primary magnets are neatly arranged under the action of the magnet, so that the end of the magnet near the ground has the opposite polarity of the magnet and attracts each other. This shows that iron can be magnetized by magnets due to the presence of primordial magnets.

The structure of the steel is altered during the heat treatment process, and there are fewer primary magnets, so they cannot be attracted to the magnets.

It is determined by the characteristics of the magnet.

If it is explained by atomic current, it means that the magnetic field generated by the electric current magnetizes other objects, and the magnetized objects produce an electric field.

The electric field interacts with each other to produce the action of force.

Matter is mostly made up of molecules, which are made up of atoms, which in turn are made up of nuclei and electrons. Inside the atom, the electrons rotate incessantly and revolve around the nucleus. Both of these motions of electrons produce magnetism.

But in most matter, the direction of electron movement is varied and chaotic, and magnetic effects cancel each other out. Therefore, most substances are not magnetic under normal conditions.

Ferromagnetic substances such as iron, cobalt, nickel or ferrite are different, and the electron spins inside them can be spontaneously arranged in a small area to form a spontaneous magnetization region, which is called a magnetic domain. After the ferromagnetic material is magnetized, the internal magnetic domains are arranged neatly and in the same direction, so that the magnetism is strengthened, and the magnet is formed. The magnet magnetizes the magnet, and the magnetized iron and the magnet have different polarities of attraction, and the iron is firmly "glued" to the magnet.

Let's say that magnets are magnetic. （

Talk nonsense! Steel can be sucked! In addition to stainless steel!
