Strontium Ferrite Magnet Y30BH Radial Magnet
Permanent magnet ferrite is a hexagonal structure with uniaxial anisotropy. Mainly barium, strontium and lead ferrite and its composite solid solution. Because this kind of ferrite material can remain strong and constant remanent magnetic properties for a long time after the disappearance of the external magnetic field, it can be used to generate stable magnetic field in the external space.
A magnet that travels along a radius is called a radial magnet. It's usually a circular ring, with a magnetic pole on the outside and a magnetic pole on the inside.
Although the magnetic field of the magnet does not harm the human body, direct contact with the powerful radial magnet itself may cause direct harm to the human body.
The direct opposite of the radial magnet may cause entrainment, especially the ndfeb strong magnet and large magnet.
Roughly speaking, as long as it is "ferromagnetic substance", is a magnet to attract ferromagnetic material, test indicate that any material in the outside magnetic field can be more or less to be magnetized, only varying degrees of magnetization.
According to the properties of materials in the external magnetic field, radial magnets can be roughly divided into three categories: paramagnetic materials, diamagnetic materials and ferromagnetic materials. On the basis of molecular current hypothesis, material should be reflected in the magnetic field broadly similar features, but in this notice we material features in different outside magnetic field is very large, it reflects the limitations of molecular current hypothesis.
In fact, there are differences in the microstructure of various substances, and the difference in the magnetic structure of such substances is the cause of the difference in the magnetic properties of substances. We call paramagnetic materials and diamagnetic materials weak magnetic materials, and ferromagnetic materials strong magnetic materials. Generally speaking, radial magnets refer to strong magnetic materials. According to the difficulty of demagnetization after magnetization, magnetic materials can be divided into soft magnetic materials and hard magnetic materials.
The substance that radial magnet removes magnetism simply after magnetization is called soft magnetic material, the substance that does not touch simply is called hard magnetic material. Generally speaking, the remanence of soft magnetic materials is small and that of hard magnetic materials is large.
