   ===========================   
   if so   
   how is it that a permanent magnet   
   don t violate conservation of energy ???:   
      
   there is there some nonstop movement of something   
   that can even do some work :   
   (like   
   attracting/moving along a distance   some piece of iron mass- along some   
   distance   
   and still   
   -''no violation of conservation of energy'' ??!!

   [[Mod. note -- No violation of conservation of energy here, any more   
   than there would be if that piece of iron mass slid down a slope.  In   
   both cases you have a system with some potential energy, which is used   
   to do work (and in which frictional forces result in that potential   
   energy being converted to heat as the iron mass slides).
