I was wondering if magnets run out of power, or more properly stated, cease to 
become magnets?  I have a small magnet (out of speaker, I think) that I have 
had since I was about 3.  Still works, seems to be as strong as ever.  Will it 
become a piece of rock in another 100 years, or can it last even longer?
