  2. Balance the bar on your hand/something and if it try to move and point to north/south, then it is magnet, else iron bar.

  3. hang it from a rope and it will tend to point in the north-south direction.

  4. Break it into two and test if it repels/attracts its other part.

  5. Move one end of a bar over the other bar if the strength of attraction varies then the other bar is iron, otherwise it is a magnet.
