NdFeB magnet:
A permanent magnet is an object made from a material that is magnetized and creates its
own persistent magnetic field. These include the elements iron, nickel and cobalt, some
alloys of rare-earth metals, and some naturally occurring minerals such as lodestone.
Although ferromagnetic (and ferrimagnetic) materials are the only ones attracted to a
magnet strongly enough to be commonly considered magnetic, all other substances
respond weakly to a magnetic field, by one of several other types of magnetism.
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
One of the most important features of an electromagnet is the ability to change its magnetic
force. When no electric current flows through the magnet's wires, it has no magnetic force.
Put a little current in the magnet, and it has a small force. A large current gives the
magnet a bigger force, able to lift or pull heavier objects. The ability to turn magnetic force
on and off has many important uses, ranging from simple household gadgets to giant industrial
machines.
The pulling power of a permanent magnet is limited to the type of metal from which it's made.
Currently, the strongest permanent magnets are made of a combination of iron and a metal
called neodymium. Although these permanent magnets are strong, the best electromagnets
are more than 20 times stronger.
