Overview

• Ningbo Tengxiao Magnetic Industry Co., Ltd. is a professional supplier of magnetic products and magnetic equipment, specializing in the production of high-quality NdFeB magnets, magnetic badges and other magnetic equipment as well as customized magnetic office supplies.

  Simply put, magnetism means that a substance will be subjected to magnetic force when placed in an uneven magnetic field. In the same inhomogeneous magnetic field, the direction and strength of the magnetic force per unit mass of the material determines the magnetic strength of the material. Because any substance has magnetism, any substance will be subjected to magnetic force in an uneven magnetic field.

  What really exists in the space around the magnetic poles is not the lines of magnetic force, but a kind of field, which we call a magnetic field. The mutual attraction of magnetic substances, etc. is carried out by the magnetic field. We know that there is universal gravitation between matter, which is a kind of gravitational field. Similar to the magnetic field, it is a field that fills the space around the magnetic pole. The strength of the magnetic field can be represented by the number of imaginary magnetic lines of force, where the magnetic field lines are dense, the magnetic field is strong, and the magnetic field lines are weak. The number of magnetic field lines passing through a unit section is called the magnetic flux density.

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

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