Magnet's attraction force on a piece of iron

Click For Summary
When an iron piece is placed near the north pole of a natural magnet, it becomes magnetized due to the alignment of its internal magnetic domains, resulting in an attraction force. The strength of this attraction can be calculated using the magnetic equivalent of Coulomb's law, which requires knowledge of the pole intensity (m) of both the magnet and the iron piece. The pole intensity of the bar magnet can be determined through experiments, such as measuring neutral points. Once the iron piece is magnetized, its pole intensity can also be measured to calculate the force of attraction accurately. Understanding these principles is essential for analyzing magnetic interactions effectively.

Hi everyone,
Please describe the process accures when placing an iron piece in front of (north pole) natural magnet bar, and how the attraction force is created.
Also, to calculate the force magnitude (coulomb law for magnetism formula) how can I determine the piece of iron pole intesity (m) after it became a magnet itself? (I assume that pole intensity (m) of bar magnet is known or could be detemine by neutral points experiment & measuring)
Thank you all
