Why is the magnet magnetic, is there any way to make it non magnetic!!

The main component of the magnet is ferrite, and the electron spins inside it can be spontaneously arranged in a small range to form a spontaneous magnetization region, which is called the magnetic domain. After the ferromagnetic material is magnetized, the internal magnetic domains are neatly arranged in the same direction, so that the magnetism is strengthened, and it constitutes a magnet.

The creation of the geomagnetic field is still divided in the scientific community, and there is no convincing theory for most people. However, the dominant theory is as follows: All physical phenomena in nature are the result of the movement and change of all matter, from the universe to protons, neutrons, electrons, etc.

The earth is a star with a very high density close to the spherical shape, the gravitational field of the earth is very large, the gravitational field is ** in the center of the earth's core, the density of the center of the earth's core is very large, the earth's core has a huge attraction to the objects on the earth's surface and the surrounding objects, prompting the earth's surface and its surrounding objects to move closer to the center of the earth's core, and causing great pressure. The closer to the center of the earth's core, the greater the pressure of the object, the greater the pressure around the center of the earth's core, the great high pressure and high temperature are generated, under the high temperature and high pressure, the matter around the core of the earth undergoes complex changes and movements, due to complex changes and movements, the formation of a streamlined particle flow of smaller particles such as molecular clusters, atomic clusters or atoms, due to the violent movement, violent collision and friction between each other, the formation of charged particles. The mass of these streams of particles is almost concentrated in the nucleus, which is positively charged.

Under the high-speed west-to-east rotation of the earth itself, the fluid-like flow of charged particles formed in the vast space around the earth's core will move at high speed from east to west around the axis of the earth's core in the north-south direction (high-speed rotational motion). Due to the directional rotational motion of the flow of charged particles, according to the theoretical analysis of the current magnetic field, magnetic poles are generated at the north and south ends of the earth's core, forming a strong electromagnetic field, which is the reason for the generation of geomagnetic fields. Heating can be demagnetized.

When the temperature rises to a certain level, it loses its magnetism, but it takes a while to heat up.

We know that an atom is made up of a positively charged nucleus and negatively charged electrons revolving around the nucleus. Electrons not only revolve around the nucleus, but also spin, and these movements of electrons in microscopic particles such as atoms and molecules form a "molecular circulation". In the interior of a magnet, such molecular circulation is arranged in one direction, and the n and s poles are shown on the macroscopic scale, that is, they have magnetism.

The molecular circulation of other substances is arranged in a haphazard manner, and the resulting magnetism cancels each other out, so there is no magnetism in general.

There are many types of stones that are colored, but not magnetic, and a more specific description is needed to determine which kind of stone it is. A few possible stone types are listed below.

1.Coral: Corals are marine creatures that are colorful but not magnetic.

2.Tourmaline: Tourmaline is a highly transparent gemstone that comes in a variety of colors, including blue, yellow, green, pink, etc., and is also not magnetic.

3.Turquoise: Turquoise is a kind of gemstone with green, blue-green and blue colors, which is slightly inferior to tourmaline in hardness, and also does not disturb magnetism.

4.Ruby: Ruby is a red gemstone that is not magnetic.

In conclusion, there are many types of stones that have color but are not magnetic, and the above list is a few of the common ones.

Summary. Iron meteorites contain iron and nickel, which are two metals that are easily magnetized, and there is another metal in nature, cobalt, which is also easily magnetized, known as the "iron triangle", because the d orbitals of these three metals contain unpaired electrons, so they are easily magnetized. The Iron Triangle itself is not magnetic, and no magnetic material has been found in meteorites so far, and all meteorites are not magnetic.

Magnetic substances are called permanent magnets (magnets), which can produce magnetic fields, commonly known as magnets, and if the substances that are easily magnetized are placed in the magnetic field, they will react (attract or repel each other), and iron (such as coins) can be attracted by magnets because iron is easy to be magnetized, and the substances that are easy to be magnetized are called ferromagnetic materials. Copper cannot be magnetized, so copper is not a ferromagnetic material.
