NdFeB magnet:
  

Permanent magnets are materials where the magnetic field is generated by the internal structure of the material itself. Inside atoms and crystals you have both electrons and the nucleus of the atom. Both the nucleus and the electrons themselves act like little magnets, like little spinning chunks of electric charge, and they have magnetic fields inherent in the particles themselves. There's also a magnetic field that's generated by the orbits of the electrons as they move about the nucleus. So the magnetic fields of permanent magnets are the sums of the nuclear spins, the electron spins and the orbits of the electrons themselves.  Permanent magnets are limited by the structure of the material. And the strongest magnetic field of a permanent magnet is about 8,000 gauss. The strongest magnets here at the Magnet Lab are 450,000 gauss, which would be almost 50 times stronger than that.

The production process
Neodymium magnets are actually composed of neodymium, iron and boron (they are also referred to as NIB or NdFeB magnets).  The powdered mixture is pressed under great   pressure into molds.  The material is then sintered (heated under a vacuum), cooled, and then ground or sliced into the desired shape.  Coatings are then applied if required.  Finally, the blank magnets are magnetized by exposing them to a very powerful magnetic field in excess of 30 KOe.

Advantages of Sintered Magnet
1.The NdFeB magnet has high remanence, high coercive force, high energy product and high ratio between performance value and product cost.
2.It can be easily formed into various sizes.Various shapes on offer: block, round, ring, arc-even highly complex forms. Virtually any shape of neodymium
3.Smaller size and lighter weight in designing devices
4.High energy range from 30MGOe to 53MGOe with wonderful coercive force

 Application
ceramic materials, chemicals and pharmaceuticals, machinery and electronics, paint pigments, food processing, textile and other industries.
building materials industry, mud iron
iron machinery and equipment caused by iron mill. 
the food processing industry process in addition to iron
silicon carbide abrasive industry, corundum, quartz sand, aluminum powder. Zirconium silicate powder iron removal process.
batteries, pharmaceuticals, refractories industry production process in addition to iron

Coatings
Neodymium magnets are a composition of mostly Neodymium, Iron and Boron. If left exposed to the elements, the iron in the magnet will rust. To protect the magnet from corrosion and to strengthen the brittle magnet material, it is usually preferable for the magnet to be coated. There are a variety of options for coatings, but nickel is the most common and usually preferred. Our nickel plated magnets are actually triple plated with layers of nickel, copper, and nickel again. This triple coating makes our magnets much more durable than the more common single nickel plated magnets. Some other options for coating are zinc, tin, copper, epoxy, silver and gold. Our gold plated magnets are actually quadruple plated with nickel, copper, nickel and a top coating of gold.

Caution:
Neodymium magnets can be dangerous, as they generate extremely strong pull forces, therefore must be handled with care to avoid personal injury and damage to the magnets. Fingers and other body parts can get severely pinched between two attracting magnets. Neodymium magnets are brittle, and can shatter if allowed to slam together, launching small pieces at great speeds. Eye protection should be worn when handling there magnets.
