Magnets are nothing but attractive. Because of their gravitational forces, they are widely used in various industries. Strong magnets are the permanent magnets we often say. They are small in size, light in weight and strong in magnetic properties. It is the best magnet to date.

As a third-generation rare earth permanent magnet material, the strong magnet has a high performance-price ratio. It is widely used in energy, transportation, machinery, medical, IT, home appliances and other industries, especially the development of knowledge economy represented by information technology. It will bring new uses to functional materials such as rare earth permanent magnet industry, which will bring a broader market prospect to the NdFeB industry.

The strong magnet has a special force. Like electricity, the magnet is not visible to human magnetism, but its influence is everywhere. Magnets are easily made and their use is quite common. The size of the magnetic field can be represented by the number of imaginary magnetic lines of force. The denser the magnetic field lines are the stronger the magnetic field, and the weaker the magnetic field is.

When strong magnets moves, the charged particles are subjected to a kind of Lorentz force in the magnetic field. The strength of the magnetic field is distinguished by the strength of the magnetic force of the magnetic particles in the different magnetic fields. The application of magnets is very common in our lives, such as the use of magnets in the packaging box. Tesla is an international unit dedicated to measuring magnetic flux density. The density of the magnetic flux is the basic physical quantity describing the magnetic field, and the magnetic field strength is the auxiliary quantity describing the magnetic field.
