From a source it is supposed:
Take 0000 dry steel wool with gloved hands pull the loaf into two halves. Rub the halves together over a paper or paper plate and collect "debris" of filings. Store in a dry glass jar with lid to prevent rusting as it will oxidize relatively quickly .
Depends on the size of the filings. The surface tension of water (attraction of water particles to themselves on the surface) can hold small and light weights. That's why certain insects can "walk on water"
Well you can buy it or extract it yourself.
You can find chemical supply houses that sell to educational institutions or the general public. They should carry iron fillings.

You can look up local machine shops in your area. Sometimes as part of the process of grinding iron they'll produce quite a bit of iron filings. You may be able to get some free.
Or you can extract it from dry soil or sand in your backyard or elsewhere. Stuff is found pretty much anywhere.

Iron filings may be pure elemental iron, it depends on the source of the iron.
pure substance
Fine iron filings
If they are iron filings, you can use the property of magnetism to remove the iron filings using a magnet. You will need to rinse the iron filings with water after you remove them with the magnet in order to completely remove the sawdust from them.
When sufficiently heated, iron filings and sulfur react to produce a compound, iron (II) sulfide.
Copper filings are not attracted to a magnet, as iron filings are.
Iron filings may be pure elemental iron, it depends on the source of the iron.
pure substance
magnetic separation.
iron
Sulfur and iron filings together are a mixture.
Fine iron filings
Pure iron filings will be attracted to a magnet; but pieces of iron carbonate will not.
separate iron filings AND ash from water by filtration or evaporation then, if required, separate iron filings from ash by using a magnetic field,
If they are iron filings, you can use the property of magnetism to remove the iron filings using a magnet. You will need to rinse the iron filings with water after you remove them with the magnet in order to completely remove the sawdust from them.
A magnet should be very good at picking out the iron filings.
No, iron filings are not a mixture
