By sprinkling iron fillings around a magnet the magnetic field can be shown. If the magnet is the opposite charge then the iron they will be repelled by the magnet showing how far the magnetic field reaches.
With a magnet or by sprinkling iron fillings an cardboard if you use it to see the pattern of magnetic field.
The poles.
You can use a magnet to attract and separate the iron fillings from the sawdust. Place the magnet in the mixture and move it around to attract the iron fillings. The sawdust will not be affected by the magnet and can be separated from the iron fillings.
Iron fillings are made up of small magnetic domains that align themselves with an external magnetic field due to the magnetic forces between the fillings and the field. This alignment results in the fillings forming patterns in the direction of the magnetic field lines, making the field around a magnet visible.
To separate sawdust and iron fillings, you can use a magnet to attract and separate the iron fillings from the sawdust. The iron fillings will be drawn towards the magnet, allowing you to easily separate them from the sawdust.
The fillings align themselves according to the magnetic field created by the magnet. *See the related links to images of the fillings behaving this way, along with a drawing representing the magnetic fields to which the filings align. You can see how the fillings behave similarly in each of the different photos. (see also related question below)
use a magnet
The iron fillings will align with the magnetic field produced by the magnet, forming elongated patterns along the field lines. They will cluster around the poles of the magnet, where the magnetic field is the strongest.
Yes, you can separate sulfur and iron fillings using a magnet. The iron fillings will be attracted to the magnet and can be separated out, leaving the sulfur behind.
Simply use a magnet. If the magnet is strong enough, you can simply hold it just above the sawdust and the fillings will come zooming out and onto the magnet. If it is kinda weak, put it in the sawdust and remove. Either way, the fillings will be on the magnet. (Sorry,I didn't realize that I had entered this without logging in.

To separate iron fillings from sulfur, you can use a magnet to attract the iron fillings as they are magnetic and can be easily picked up. Sulfur does not respond to magnets, so the iron fillings can be separated by simply utilizing the magnet.
Use a magnet. The magnet will remove the iron filings form the sand.
