Artificial Magnets: divided horseshoe magnets and bar magnets, the most common is that we live in, where the more popular horseshoe magnet. Means the side of a single magnet magnetic magnets weak magnetism other side, the method is treated with a special double-sided galvanized steel side magnets package, and it was wrapped side of the magnetic will be masked to the other side is refracted force, other side of the magnetically enhanced. If the occasion requires only one side is magnetic, the other side may cause damage or any magnetic interference; some occasions, such as a magnet on the box side magnetic only need one side and dispensable, there is no use of magnetic, Such single-sided magnet will greatly reduce costs and conserve magnetic materials. Like single-sided magnet magnetic refraction refraction of the signal satellite pot or pan flashlight light refraction of light, its refraction effect is mainly determined by the following three aspects: 1. Material: material selection and thickness, as well as the spacing of the magnet and the material is closely relationship. Pure iron is easy MFL, with a special treatment refraction will increase, but not 100% shielding material developed, but different manufacturers do material effect is different.
2. Angle: According refraction, curved material works best material refraction angle larger loss.
3. Space: the magnetic field lines in the air as the cell phone signal, you need to have space to refracted. Torch light bulb pot as completely wrapped in, use the effects are bad, because there are plenty of light refraction is loss.
How can we make use of overband magnetic separator the above principle, the magnetic enhancement works best is that many parameters for the best, a lot of manufacturers are doing repeated experiments, such as Xian Guotai magnet factory-sided magnetic treatment best result is enhanced 50% so in areas such as packaging bags will greatly reduce production costs and savings magnetic materials.

Magnets classification
Magnets can be grouped into "permanent magnet" and "non permanent magnets." The permanent magnet may be natural products, also known as natural magnet can also be manufactured by hand (the strongest magnets are neodymium magnets). The permanent magnet, and only in certain conditions be magnetic, usually produced in the form electromagnet, which is to strengthen the magnetic field by the current.
Concept
Soft including silicon Grate Magnets and soft core; hard magnetic including Alnico, SmCo, ferrite and neodymium, of which, the most expensive is samarium cobalt magnet, the cheapest is ferrite magnet, NdFeB magnets are the highest performance, but the most stable performance, the temperature coefficient is the best alnico, the user can choose according to the different needs of different hard magnetic products.
We said magnet, generally refers to permanent magnets.
Permanent magnet is divided into two major categories.
The first category
Metal alloy magnets including NdFeB magnet Nd2Fe14B), samarium cobalt magnets (SmCo), Alnico magnet (ALNiCO)
The second category
Ferrite permanent magnet material (Ferrite)
1. It is found in NdFeB magnets commercialization highest performance magnets, known as Magneto, with a high magnetic its maximum energy product (BHmax) higher than ferrite (Ferrite) 10 times or more. Its own machining performance is also quite good. Operating temperature up to 200 degrees Celsius. And its hard texture, stable performance, good price, so its application is extremely broad. But because of its chemical activity is very strong, it must be on its surface coating. (Eg plating Zn, Ni, electrophoresis, and passivation).
2. It is the main raw materials include ferrite magnets BaFe12O19 and SrFe12O19. By law made of ceramic, texture rather hard, is a brittle material, due to ferrite magnets have good temperature resistance, low price, moderate performance, has become the most widely used permanent magnets.
3. Alnico magnet is made of aluminum, nickel, cobalt, iron and other trace metal elements in an alloy. Casting process can be processed into different sizes and shapes, workability is very good. Cast Alnico magnet has the lowest reversible temperature coefficient, operating temperature up to 600 degrees Celsius. Alnico products are widely used in a variety of instruments and other applications.
4. Samarium cobalt (SmCo) overband magnetic separator divided according to different ingredients SmCo5 and Sm2Co17. Because the material is expensive and their development is limited. Samarium cobalt (SmCo) as a rare earth permanent magnet, not only has a high energy product (14-28MGOe), coercivity reliable and good temperature characteristics. Compared with NdFeB magnets, SmCo magnet is more suitable for working in a hot environment.

Period of use magnet
Magnet in contact with the process of the fluid, the interior of the magnetic energy will produce some irreversible loss, when the loss exceeds 30% of the original strength, or the surface of the bag off of the metal, stainless steel tube rupture when worn. When faced with these situations should be timely replacement bar magnet, the Drawer magnets must not allow the magnet has been leaked to continue working. Magnets are relatively brittle, oil coated on the surface, this will impact on the environment. In China, the production of magnets can work under heavy 1-2 years, if it is to work under light load 7-8 years.

Compared with the magnetic grid grating, which differs from the same point
Grating - by optical interference and diffraction theory made of sensors. When two identical grating pitch stacked together, while allowing lined constitute a slight angle, this time in the parallel light irradiation, with engraved lines vertically symmetrical able to see light and dark stripes, called moire, so moire of light diffraction and interference effects of the overall results. When moving a little grating pitch, Grate Magnets the moire fringe moves with a fringe spacing, so that we measure the width of moire lined grating width ratio measurement much easier. In addition, since each raster moire are lined by the intersection of many components, there is a lined lined when there is an error when the (unequal spacing or inclined), this error is lined and there is another raster line pattern intersection location will make a difference. However, a moire fringe is formed by a number of raster lines on the intersection, thus a change in the catch position lined, for a moire effect in terms of its very small, so that moire can play amplification and average effect.
Magnetic scale - made use of the principle of magnetic sensors. Base feet are uniformly magnetized strip. S and N poles are arranged evenly spaced on the strip through the reading head reads S, N pole count changes.
Grating affected by temperature, the general use of the environment at 40 degrees or less taken with disabilities. (Coordinate measuring machine are generally required in a constant temperature humidity environment transverse measurements to ensure accuracy.)
Open magnetic scale easily affected by magnetic fields, closed magnetic scale does not have this trouble, but the cost is higher.

Features magnetic grid
Magnetic grid is an important feature of the magnetic scale in contact with the head of the working condition. The working principle of the magnetic grid is a magnetic-electric conversion, in order to ensure a stable head output signal amplitude, given the reluctance of air is large, the magnetic scale and the magnetic head is allowed between a large and variable clearance, preferably contact type. With this magnetic head at the time the gate is at work on the tape pressed into, Neodymium Motor Magnet so that there is not real-time with a surface smooth, the magnetic head and the tape can be a good contact. Linear magnetic grid of magnetic scale and the gap between the heads of about 0.01mm, assembly and adjustment can not be achieved because the ideal state, so in fact quasi-linear magnetic grid is also in contact working condition.Another important feature of magnetic grid is the magnetic scale in a certain tension.
