  By the above Q I remembered, is permanent magnet always permanently magnatized? Forever? does the the flux die down?
  
  And, i really dont know how magnetism works, actually no one does for sure, there are many theories, but none fixed.

  It's true that being one of the fundamental forces magnetism can not be explained in terms of other physical entities. It is best explained as an interaction of fields.
  
  Every magnetic body establishes a magnetic field around it much like gravity only unlike gravity magnetism is bipolar.
  
  Every object has magnetic property to some extent (every electron being a small magnet by nature). However, since these electrons are randomly oriented in any material, being bipolar, the effect of individual minuscule magnets cancels out. Some elements with better natural alignment of electrons exhibit what we call as magnetic nature.
  
  Hope this gives you some idea. You can always refer books for detailed understanding.
