some magents can last for a 1000YEARS. meaning they lose about 1% per decade. 10x100=1000. Some magnets can last indefinately. obviously if all magnets lost their charge in a 1000YEARS we wouldn't be finding so many in nature.ome magents can last for a 1000YEARS. meaning they lose about 1% per decade. 10x100=1000.
