Will neodymium magnets lose their strength over time?

Very little. If they are properly handled, which includes not overheated or physically damaged, our neodymium magnets will lose less than 1 percent of their strength over 10 years. This is not enough to notice without very sensitive measuring equipment. In addition, the neodymium magnets we offer will not lose their strength even if they are held in repelling or attracting positions with other magnets over long periods of time.
