Detailed Solution

Boojho dipped a bar magnet into a heap of iron filings and pulled it. He discovered that iron filings become attracted to the magnet, as shown. The end regions of a magnet are called poles.
Magnetic field lines flow through the magnet and the magnetic poles are at the ends in the case of a bar magnet. They appear to be coming from the north pole and entering the magnet through the south pole. The size of the magnetic field is observed to be greatest at the poles and decreases as we move away from the poles. The bigger the magnitude of the magnetic field, the stronger the attraction to other magnets or metals. As a result, when we dip a bar magnet in iron filings, the poles of the magnet attract the majority of the filings. Magnetic poles are the ends of the magnet that have the most iron filings stuck to them.
