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, 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.

Grades of Neodymium Magnet
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.
N series: N35 N38 N40 N42 N45 N48 N50 N52- 80°C
M series: 35M 38M 40M 42M 45M 48M 50M-100°C
H series: 30H 33H 35H 38H 40H 42H 44H 46H 48H-120°C
SH series: 30SH 33SH 35SH 38SH 40SH 42SH-150°C
UH series: 28UH 30UH 33UH 35UH 38UH 40UH-180°C
EH series: 28EH 30EH 33EH 35EH-200°C
AH series: N28AH N30AH N33AH N35AH-220°C
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.
Neodymium magnets are over 10x stronger than the strongest ceramic magnets. If you are currently using ceramic magnets in your project, you could probably use a much smaller neodymium magnet and have greater holding force.
