How will you recognize the magnet & magnetic material & non-magnetic material?

Submitted by: Muhammad

Drag one piece of material over another. There is no attractive force in the middle portion of the magnet. OR Get a piece of thread and tie up with the one bar and check for poles. If it iron bar then it moves freely and if it is magnetic bar then it fix in one direction according to poles.
