So each particle of iron becomes magnetised and behaves like a tiny bar magnet. That means it will align with the direction of the magnetic field in its vicinity.
The friction with the paper holds them in place. If you attempted this floating in space, e.g. aboard the International Space Station the filings would all stick to the ends of the magnet.
If we start introducing iron filings to a bar magnet, will the pattern begin from the poles and slowly grow to the equatorial region as we bring more and more iron filings? Further, is the pattern limited by the amount of iron filings or in other words, will we cover the entire region around the magnet with iron filings if we have surplus of filings.
