Describe a method for separating a mixture of iron filings and sulphur powder other than that by using a magnet.

A mixture of iron filing and sulphur powder can be separated by using magnet. This is because iron filling are attracted by a magnet but sulphur is not attracted by a magnet. In order to separate iron filing from sulphur powder, a horse-shoe magnet is moved over the surface of the mixture. The iron filings are attracted by the magnet, they cling to the poles of the magnet and get separated.
