NdFeB Rare Earth Countersunk Magnet,  Very little. Neodymium magnets are the strongest and most permanent magnets known to man. If they are not overheated or physically damaged, neodymium magnets will lose less than 1% of their strength over 10 years – not enough for you to notice unless you have very sensitive measuring equipment. They won’t even lose their strength if they are held in repelling or attracting positions with other magnets over long periods of time.

[A] In most applications, the answer is simply “no”. If the magnets will be exposed to higher temperatures while in repelling applications, the answer is “possibly”. The exact answer is a bit too complicated for a FAQ answer, and requires specifics about the application.
[Q] Are your Neodymium Rare Earth Magnets RoHS compliant?
[A] 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).
