Is there any magnetism in glassy meteorites? Is glassy meteorites transparent?
Magnetic material is divided into two kinds of metal and nonmetal according to its properties. The former mainly include electrical steel, nickel base alloy and rare earth alloy, etc. the latter is mainly ferrite material. It is divided into soft magnetic material, permanent magnetic material and functional magnetic material according to its use. Functional magnetic materials are mainly magnetostrictive materials, magnetic recording materials, magnetic materials, magnetic materials, magnetic materials, magnetic materials and magnetic rotary thin film materials, reflecting the basic magnetic properties of magnetic materials with magnetization curves, hysteresis loop and magnetic loss etc.. Meteorites are fragments of other objects from the solar system outside the earth, mostly from asteroids between Mars and Jupiter, with a small number from the moon (40 pieces) and Mars (40 pieces). More than 40 thousand meteorites have been collected worldwide. They can be broadly divided into three categories: stony meteorites (mainly silicates), iron meteorites (iron nickel alloys), and stony iron meteorites (iron and silicate mixtures).
Not necessarily. The magnetic material has a strong magnetic order, and the broad sense includes weakly magnetic and antiferromagnetic materials that can be applied to their magnetic and magnetic effects. Magnetism is one of the basic properties of matter. Matter can be divided into diamagnetic, paramagnetic, ferromagnetic, antiferromagnetic and ferrimagnetic substances in terms of their internal structure and their properties in an external magnetic field. Ferromagnetism and ferrimagnetic substances are ferromagnetic substances, diamagnetic and paramagnetic substances are weak magnetic substances.
There are all kinds of styles. Rock iron meteorites are composed of iron, nickel and silicon, acid and salt minerals. The content of iron and nickel is 30 to 65. These meteorites account for about 1.2 of the total amount of meteorites, so the commercial value is the highest. Such meteorites contain more than 70% iron, followed by silicon, aluminum and nickel, the main minerals are cone stone, nickel stone, stone and so on, the main minerals for meteorites iron, chromite, graphite and so on. According to the main internal composition and structural characteristics of the iron and stone meteorites, they are divided into olivine stone, iron meteorite (PAL), iron meteorite (MES), bronze pyroxene quartz stone, iron meteorite. A silicate mineral, such as olivine, pyroxene, and a small amount of plagioclase, that also contains a small amount of metallic iron, sometimes more than 20. Density 3 to 3.5.
