If i had magnet and i would put piece of iron under it just right so it wouldnt fall nor rise but it would float would it eventualy fall anyway? If so why?

Would the magnetic field "demagnetize" the iron after time or the magnet itself would get weaker?...

The situation that you describe, an iron piece suspended in mid-air by a magnet overhead, would be extremely unstable. Any slight perturbation in the system (small changes in air currents, vibrations, temperatures, etc.) would cause the iron to either fall to the ground, or move upward into the magnet.

If we ignore these perturbations, then eventually the iron piece would become magnetized as more of its magnetic domains aligned with the magnetic field of the overhead magnet. This would cause the iron piece to become more strongly attracted to the overhead magnet and the iron would move upward.
