50 PCS Neodymium Magnet Cylinder [8x4mm]

Description:
A neodymium magnet (also known as NdFeB, NIB or Neo magnet), is the most widely used type of rare-earth magnet, which is a permanent magnet made from an alloy of neodymium, iron and boron to form the Nd2Fe14B tetragonal crystalline structure.
There are two principal neodymium magnet manufacturing methods: Classical powder metallurgy or sintered magnet process and Rapid solidification or bonded magnet process.
The basic shapes of neodymium magnets are blocks, arc segments (used mostly in DC motors), discs, cylinders and rings.
Neodymium magnets are graded according to their maximum energy product, which relates to the magnetic flux output per unit volume. Higher values indicate stronger magnets. For sintered NdFeB magnets, there is a widely recognized international classification. Their values range from 28 to 52. The first letter N before the values is short for neodymium, meaning sintered NdFeB magnets. Letters following the values indicate intrinsic coercivity and maximum operating temperatures (positively correlated with the Curie temperature), which range from the default (up to 80 °C or 176 °F) to AH (230 °C or 446 °F).
