Q:Magnetic oxide materials and metal magnetic materials
Magnetic material can be easily divided into soft magnetic material and hard magnetic material after magnetization. (3) magnetic material can be divided into metal magnetic material and ferrite according to chemical composition. The metal soft magnetic material with soft iron, silicon steel, nickel alloy. The metal hard magnetic materials are carbon steel, tungsten steel, aluminum nickel cobalt alloy. Soft ferrite with Mn Zn ferrite, nickel zinc ferrite etc.. The hard ferrite has barium ferrite and strontium ferrite.
Q:What are the factors that determine the coercivity and remanence of magnetic materials? Are there any links between these factors? What is the connection?
The residual magnetic Br: compares the magnet to a sponge, and the remanent magnetism is like a sponge absorbing and saturated. At this time, the magnetic value of the magnet is displayed;
Q:What metal materials are non ferromagnetic materials?
Ferromagnetic materials such as iron, cobalt, nickel and manganese, as well as gadolinium, terbium, etc. behind lanthanides, and alloys formed between them and other metals, nonmetals, or their own metal oxides, are also ferromagnetic
Q:Basic properties of magnetic materials
The magnetic material is composed of ferromagnetic or ferrimagnetic material, in the magnetic field under the action of H, there will be magnetization M or magnetic induction intensity corresponding to the B, they change with the magnetic field strength H curve known as the magnetization curve (M ~ H or B ~ H curve). The magnetization curve is nonlinear in general and has 2 characteristics: magnetic saturation and hysteresis. When the magnetic field intensity H is large enough, the magnetization M reaches a certain saturation value Ms, continue to increase H, Ms remained unchanged; and when the value of M reached saturation, the external magnetic field H is reduced to zero, M does not restore to zero, but along the MsMr curve. The working state of the material is equivalent to the M to H curve or a point on the B to H curve, which is often referred to as the work point.
Q:How to increase the magnetism of a magnet?
When the direction of each domain is uniform, the whole material shows magnetism. The so-called magnetization is to make the magnetic domain of the magnetic domain in the magnetic material become consistent. When the material that does not exhibit magnetism is placed into another strong magnetic field, it is magnetized, but not all materials can be magnetized, and only a few metals and metal compounds can be magnetized.
Q:Is it possible for Cu species to be magnetic?
From the application function, the magnetic material is divided into: permanent magnet material, soft magnetic material, magnetic recording - moment magnetic material, spin magnetic material and so on. Soft magnetic materials, magnetic materials, magnetic recording materials in magnetic moment both metal material and ferrite material; and the rotating magnetic material and high-frequency soft magnetic materials is ferrite material, because the metal will produce large eddy current effect in high frequency and microwave frequency, resulting in metal magnetic material can not be used, and the resistivity of ferrite is very high, will effectively overcome this problem, widely used.
Q:How is the magnetism of a magnet produced?
The principle of magnetic material is divided into many small areas, each tiny area is called a magnetic domain, each magnetic domain has its own magnetic distance (that is, a small magnetic field).
Q:What are hard magnetic materials and soft magnetic materials?
A hard magnetic material, or permanent magnet, refers to a material that can remain magnetized for a long time after magnetization
Q:Does ferromagnetic material have a great influence on its temperature? What is the high temperature and low temperature?
Influence of temperature on the characteristics of magnetic core inductance, obtained under different temperature conditions the characteristic is not the same, the general operating temperature below 105 degrees. It features high temperature and then decreased significantly, high magnetic loss.
Q:Should the iron core of the electromagnet be made of hard or soft magnetic material? Why?
Because the core in the work, will collide, longer, more on the core of the electromagnet core. If you wear stress is relatively small, there is no requirement on what power, can use soft magnetic materials. In my humble opinion, please be careful.
We are s specialized in manufacturing and selling all kinds of permanent magnetic materials. We are one of the major producers of magnets with decades of producing experience. Our company has advanced production equipments, experienced personnels and reliable quality assurance system. Our quality system was certified by TUV(BM TRADA & UKAS) for ISO9001:2000.
