What is the product of the magnetic material of the magnetic component

What is the magnetic material of the magnetic assembly? Magnetic materials, commonly referred to as magnetic materials refer to ferromagnetic substances, which are ancient and widely used functional materials. Modern magnetic materials have been widely used in our lives, such as permanent magnet materials used as motors, core materials used in transformers, magneto-optical disks used as memory, magnetic recording floppy disks for computers, etc.

According to Big Bit Information, magnetic materials are closely related to all aspects of informatization, automation, mechatronics, national defense, and the national economy. It is generally believed that magnetic materials refer to substances that can directly or indirectly generate magnetism from transition elements such as iron, cobalt, nickel and their alloys. Magnetic materials can be divided into soft magnetic materials and hard magnetic materials according to the difficulty of demagnetization after magnetization. Substances that are easy to demagnetize after magnetization are called soft magnetic materials, and those that are not easy to demagnetize are called hard magnetic materials. Generally speaking, the remanence of soft magnetic materials is small, and the remanence of hard magnetic materials is large.

Experiments have shown that any substance can be more or less magnetized in an external magnetic field, but the degree of magnetization is different. According to the properties of substances in external magnetic fields, substances can be divided into five categories: paramagnetic substances, diamagnetic substances, ferromagnetic substances, submagnetic substances, and diamagnetic substances.

According to the molecular current hypothesis, matter should exhibit roughly similar properties in a magnetic field, but here we are told that the properties of matter in an external magnetic field are very different. This reflects the limitations of the molecular current hypothesis. In fact, the microstructures of various substances are different, and the differences in the material structures are the reasons for the differences in the magnetic properties of the substances.

We call paramagnetic substances and diamagnetic substances weak magnetic substances, and ferromagnetic substances as strong magnetic substances.
