Product Description
Disc Permanent Neo Rare Earth NdFeB Magnet

Neodymium magnets are most powerful of any kind of magnetic materials, Br of Neodymium magnets are much more than 11,000 Gauss.  Neodymium magnets have strong holding strength on metal surface and could be used as component for holding, separating, Head actuators for computer hard disks, Head actuators for computer hard disks etc.
Neodymium magnets must be carefully handled to avoid personal injury and material damage due to its extremely magnetic strength and brittle property.
