Spherical boundary reaction in a magnetic field
Magnet is an important part of the permanent magnetic cylinder magnetic separator, which directly affects the taste after ore magnetic separation. Then the magnetic field distribution has become the main object of business research. Recently, a new type of curved magnetic field technology has been adopted. Rong researched gradually after the study.
The magnetic field distributed around the magnet is generated by the spin electrons inside the magnet. According to the high school physics knowledge, the direction of the magnetic pole is known, and the direction of rotation of the electron can be determined. A magnetic field is a substance. Many people think of a magnetic field as wind and water. As long as they are aligned with the same magnetic pole, they can produce directional torque. This is a misunderstanding of the magnetic field.
The magnetic field is not pressed into the turbine fluid, nor is it a strong wind that drives the solar blades. The magnetic field has its own characteristics. The following describes the magnetic field characteristics: the spherical boundary effect.
The so-called arc boundary effect means that the magnetic field extends from the inside to the outside by a spherical surface (or a mushroom surface) whose radius gradually increases. You can imagine it as a wave. When the two waves are close to each other, a repulsive force is generated. You can understand that the two balloons are close to each other. As the distance is shortened, the repulsive force gradually increases. When the two waves are close to each other, suction will be generated. At this time, you cannot understand it as a rubber band, because as the distance is shortened, the suction of the rubber band will decrease, and the suction of the opposite magnet will increase. The characteristics are like the earth. The closer the gravity is, the smaller the gravity is.
The spherical properties indicate that any magnetic field force can be broken down into two opposing forces. That is, at any point, it will contain a positive force and a reverse force. According to the spherical boundary effect of the magnetic field, any magnetic motor model constructed based on a simple isotropic magnet cannot work. Since the isotropic magnets are close to each other, as long as they obstruct the natural distribution of the magnetic field, a reverse repulsion is generated.
Let the one-wave forward output be Wf, the reverse output be Wb, and let Wf>Wb. Take the work path as the research object, set O point as the stress balance point (ie, the closest point of the magnetic field), point A to point 0 is the reverse output force, point 0 to point B is the forward output force, when the rotor starts from 0 point When it reaches point A, it starts to do negative work. When the rotor runs close to point O, the force F is maximum. If the rotor can cross the equilibrium point,
Fo+>Fo-
Because of the spherical effect, Fo+ also produces a reverse force at A-0, so the rotor cannot cross the equilibrium point.
In the same way, the opposite sex attracts the magnetic motor and the rotor will eventually fall to the equilibrium point (end point).

We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting
Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.
While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.
