FAQ
1. Which is the strongest type of magnet? 
     Neodymium (more precisely Neodymium-Iron-Boron) magnets are the strongest permanent magnets in the world.
2.  Is one pole stronger than the other? 
      No, both poles are equally strong.
3. What materials can I use to block/shield magnetic fields?
Magnetic fields cannot be blocked, only redirected. The only materials that will redirect magnetic fields are materials that are ferromagnetic (attracted to magnets), such as iron, steel (which contains iron), cobalt, and nickel. The degree of redirection is proportional to the permeability of the material. The most efficient shielding material is the 80 Nickel family, followed by the 50 Nickel family.
4.  Can you supply monopole magnets?
 No, we don't, nor does anyone else, because they don't exist.  All magnets must have at least two poles.
5.  What are neodymium magnets?  Are they the same as "rare earth"?
Neodymium magnets are a member of the rare earth magnet family. They are called "rare earth" because neodymium is a member of the "rare earth" elements on the periodic table. Neodymium magnets are the strongest of the rare earth magnets and are the strongest permanent magnets in the world.
6.  Are your Neodymium Rare Earth Magnets RoHS compliant? 
Yes, our magnets are fully RoHS compliant, meeting the European Parliament Directive entitled "Restrictions on the use Of Hazardous Substances" (RoHS). This Directive prohibits the use of the following elements in electrical/electronic equipment sold after 7/1/2006: cadmium (Cd), lead (Pb), mercury (Hg), hexavalent chromium (Cr(VI)), polybrominated biphenyls (PBBs) and polybrominated diphenyl ethers (PBDEs).
