We all understand that there are two magnets , which are "permanent magnet " with " non- permanent magnets ." Permanent magnets can provide natural products , do not more lodestone , also can be made manually .
Iron , cobalt, nickel, and permanent magnets such as ferrite ferromagnetic substances have appeared inconsistent, its inside electron spin can be lined up in a small area , the emergence of a spontaneous magnetization area , this area is called the spontaneous magnetization of magnetic domains . Magnetization of ferromagnetic substances , the inside of the magnetic domains neat and orderly , lined up the same direction , so that the magnetic numbers , it becomes a magnet . Atomic nuclei and electrons but also for the . Inside the atomic and electronic continuously rotation, but also rotate around the nucleus . Both the electron magnetic action will occur . However, in most of the material , the direction of electron motion is also inconsistent , disorderly , magnetic efficiency needed to offset each other . So , a lot of material in normal conditions , sometimes there is no magnetic it.
Magnet attracts iron does not go magnetization step is to iron , magnetized iron and magnet polarity between different attractive appearance , iron magnet stick very closely together . This magnet will have a magnetic .

Permanent magnet means has been found and applied first in history , which is made ​​of a magnetic material is very broad class of strongly magnetic material has .

China Rare Earth Magnet Co., Ltd. is one of the world's leading manufacturer and supplier of magnet , many permanent magnet permanent magnet Company Limited and the company ordered from magnets or magnetic components.permanent magnet suppliers we want to sell , ferrite magnets, alnico magnets, samarium cobalt magnets, rubber magnets sales.

They are widely used in industries such as automotive, communications, data processing, home appliances, electronics, instrumentation , robotics , aerospace and so on.

How to choose the right magnet ? Customers often choose based on the magnetic properties of the magnet requirements and operating temperature.

Many different types of magnets , permanent magnet and soft generally divided into two categories, we are talking about magnets, generally refers to the permanent magnet magnet.
Permanent magnet magnet is divided into two major categories :
The first category are: metal alloy magnets , including NdFeB magnet Nd2Fe14B), samarium cobalt magnets (SmCo), Alnico magnet (ALNiCO)
The second category is : ferrite permanent magnet material (Ferrite)
1 , NdFeB magnet : it is found in the commercialization of the highest performance magnets , known as Magneto , with a high maximum magnetic energy product (BHmax) higher than ferrite (Ferrite) more than 10 times . Machining performance itself is also very good. Operating temperature up to 200 degrees Celsius. And its hard, stable performance , good price, so its application is extremely broad . However, because of its strong chemical activity , it must deal with its surface coating. ( Eg plated Zn, Ni, electrophoresis, passivation ) .

2 ferrite magnets : It is mainly raw materials, including BaFe12O19 and SrFe12O19. Manufacturing method made ​​by ceramic technology , texture hard, brittle materials is due to ferrite magnets have good temperature resistance , low prices , moderate performance, has become the most widely used permanent magnets.

3 Alnico magnets : an alloy of aluminum , nickel, cobalt, iron and other trace metal elements . Casting process can be processed into different sizes and shapes , good workability . Cast Alnico has the lowest reversible temperature coefficient, operating temperature up to 600 degrees Celsius. Alnico products are widely used in various instruments and other applications.

4 , samarium cobalt (SmCo) based on different ingredients into SmCo5 and Sm2Co17. Because the material is expensive and so development is limited. Samarium cobalt (SmCo) as a rare earth permanent magnet , not only has a higher energy product (14-28MGOe), reliable coercive force and good temperature characteristics. Compared with NdFeB magnets, SmCo magnets better suited to work in high-temperature environments.

Fiber Optic Cable:

In fiber optic cable, optical fibers carry digital data signals in the form of modulated pulses of light. This is a relatively safe way to send data because no electrical impulses are carried over the fiber optic cable. This means that fiber-optic cable cannot be tapped and the data stolen, which is possible with any copper-based cable carrying data in the form of electronic signals.

Fiber optic cable is good for very high-speed, high-capacity data transmission because of the lack of attenuation and the purity of the signal.

A fiber optic cable can transmit information at very high speed over a very great distance. It comprises one or more optical fibers enveloped in a thermoplastic sheath for mechanical protection.

Fiber Optic Composition:

Optical fibers consist of an extremely thin cylinder of glass, called the core, surrounded by a concentric layer of glass, known as the cladding. The fibers are sometimes made of plastic. Plastic is easier to install, but cannot carry the light pulses as far as glass.

Each glass strand passes signals in only one direction. So a cable consists of two strands in separate jackets. One strand transmits and one receives. A reinforcing layer of plastic surrounds each glass strand while kevlar fibers provide strength.

Fiber Optic Technologies

Data transmission via fiber optic cable uses a laser beam, offering very little loss over great distances. The core fiber has a higher refractive index than its cladding material, keeping the light within by avoiding multiple reflection (single-mode fiber), thus acting as a wave guide.

Fiber Optic Cable Types:

Now,many fiber optic cable suppliers provide a wide range of quality optical fiber cables with detailed fiber optic cable specifications displayed for your convenience selecting.Many types of fiber optic cable including about 250um bare fiber,tight buffer,large core glass,simplex fiber optic cable,duplex fiber cable,OM3 OM4, Indoor Outdoor cable,loose tube,breakout cable,ribbon cable,LSZH cable,armored cable,ftth cable,figure 8 aerial cable,plastic cable,hybrid and composite cable,adss cable,special cable and so on.

How to Choose Fiber Optic Cable?

Fiber optic cables are preferable to electrical cables over long transmission distances or when an electromagnetic disturbance in an industrial setting might interfere with the signal. Single-mode fibers are required for high-speed, long-distance transmission, while multi-mode fibers are suitable for low speeds and short distances.

Optical fibers have found a widespread use in optical technologies. Today is electronical high-tech applications as for example the Laser Scanning Microscopy, the sensor technology, machine vision, medical laser or military technology use flexible elements in form of optical fibers for light transfer frequently. In most cases, very special requirements to design and function of optical fiber cables are put. We realize custom-made solutions regarding the design of fiber connectors and wavelength, transceiver sale mode behavior, polarization and beam profile.This enables short decisions and high flexibility in the creation of single components as well as system solutions. FiberStore wide-ranging competence is a substantial advantage in the realization of custom solutions. Want to know more customized to fiber optic products(such as 10g fiber cable). FiberStore can supply this service.
