3. Separation by a Magnet
Iron is attracted by a magnet.This property of iron is used to separate it from a mixture. So,if a mixture contains iron as one of the constituents, it can be separated by using a magnet.For example, a mixture of iron filings and sulphur powder can be separated by using a magnet. This is because iron filings are attracted by a magnet (and stick to it), but sulphur is not attracted by a magnet. This will become more clear from the following discussion.
