Magnetic component production how to understand the main defining concepts of magnetism

Magnetic component production How to understand the main definition concept of magnetic? Simply put, magnetism is the effect of magnetic force on a substance placed in a non-uniform magnetic field. In the same non-uniform magnetic field, the magnetic strength of the material is determined by the direction and strength of the magnetic force per unit mass of the material. Because any substance is magnetic, any substance in a non-uniform magnetic field will be affected by the magnetic force.

What really exists in the space around the poles are not magnetic field lines, but a field, which we call a magnetic field. The mutual attraction of magnetic substances is carried out by the magnetic field. We know that there is universal gravitation between matter, it is a gravitational field.

A magnetic field is similar, a field that fills the space around the poles. The strength of the magnetic field can be represented by the number of imaginary magnetic lines of force. The magnetic field is strong where the magnetic field lines are dense, and the magnetic field is weak where the magnetic field lines are sparse. The number of magnetic field lines passing through a unit section is called the magnetic flux density.

Moving charged particles in a magnetic field are subjected to a force called the Lorentz force. The strength of the magnetic field is determined by the magnitude of the Lorentic force of the same charged particles in different magnetic fields. Tesla is the SI unit of magnetic flux density. The magnetic flux density is the basic physical quantity to describe the magnetic field, and the magnetic field strength is the auxiliary quantity to describe the magnetic field. Tesla (Tesla, N) (1886~1943) was a Croatian-American electrical engineer who invented transformers and AC motors.

The magnetism of matter is not only ubiquitous, but also diverse, and therefore has been widely studied and applied. The matter close to our body and the surrounding, as far as the matter in various stars and interstellar bodies, the atoms, atomic nuclei and elementary particles in the microscopic world, and all kinds of materials in the macroscopic world, all have magnetic properties of one kind or another.
