Strong magnetic boron properties

Strong magnetic boron properties

For you to introduce the professional strong magnetic bar - ndfeb quote simple to say, its price and performance and adsorption force related: magnetic magnet is material placed in the uneven magnetic field will be affected by the magnetic force.

In the same uneven magnetic field, the magnetic strength is determined by the direction and strength of the magnetic force per unit mass of the material. Because any substance is magnetic, it is subjected to magnetic forces in an uneven magnetic field.

Indicates the strength of the magnetism of the material: the magnet can attract two magnets under a piece of cardboard without touching the steel, and make their S relative to each other. Sprinkle the cardboard with fine iron powder. The iron powder will arrange itself in a series of curves.

Where the curve between N and S is continuous, that is, from N to S. Whereas S and S are mutually exclusive and cannot merge and penetrate. This phenomenon shows that there is a connection between the magnetism of a magnet. Therefore, we can assume that there is a kind of curve between the magnetic field, which represents the strength of the magnetic interaction. This imaginary curve is called the magnetic (inductive) line, and it is specified that the line starts from N and enters S. In this way, as long as there is magnetism, it continuously sends magnetic (inductive) lines into space, and the magnetic lines close to the magnetism are dense, while the magnetic lines far away are sparse. The arrangement of the iron powder is the direction of the line.

With magnetic lines, interactions between magnets can be easily described. But it must be understood that it is assumed for the convenience of our understanding and does not actually exist. What really exists in the space around magnetism is not magnetic (sensory) lines, but is called magnetic fields.

It is through magnetic fields that magnetic materials attract each other and so on. There is gravity between matter. It is a gravitational field. A magnetic field, similarly, is a field that fills the space around it. The strength of the magnetic field can be expressed by the number of imaginary lines. The number of magnetic (inductive) lines passing through a unit section is called the magnetic flux density.

On the outside of the magnet, the magnetic (inductive) line starts from N and enters S, while the internal magnetic (inductive) line starts from S and enters N. A region that exerts magnetic force (attraction and repulsion) on other magnets placed in it.

Note: 1. The magnetic field has a direction 2. The direction of the magnetic field: physics stipulates that when the small freely rotating needle is at rest, the direction of N is the direction of the magnetic field at this point.

A moving charged particle is subjected to a force called Lorentz in a magnetic field.

The intensity is determined by the lorentz force on the same charged particle in different fields.

The magnetism of matter is not only universal, but also diverse, and therefore has been widely studied and applied. Usually the magnetism of matter can be divided into weak and strong, and then according to its different characteristics, the weak magnetism is divided into anti-ferromagnetism, smooth and anti-ferromagnetism, and the strong magnetism is divided into ferromagnetism and subferromagnetism.
