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

Grades of Neodymium:
N35, N38, N42, N38SH...what does it all mean? Neodymium magnets are all graded by
the material they are made of. As a very general rule, the higher the grade (the number
following the 'N'), the stronger the magnet. The highest grade of neodymium magnet
currently available is N52. Any letter following the grade refers to the temperature rating
of the magnet. If there are no letters following the grade, then the magnet is standard
temperature neodymium. The temperature ratings are standard (no designation) - M - H
- SH - UH - EH. You find the temperature rating of each grade on our Specifications of
Neodymium Magnets Page.

Demagnetization:
Rare Earth magnets have a high resistance to demagnetization, unlike most other types
of magnets. They will not lose their magnetization around other magnets or if dropped.
They will however, begin to lose strength if they are heated above their maximum
operating temperature, which is 176°F (80°C) for standard N grades. They will
completely lose their magnetization if heated above their Curie temperature, which is
590°F (310°C) for standard N grades. Some of our magnets are of high temperature
material, which can withstand higher temperatures without losing strength.
