Detailed explanation-1: -By using a magnet, iron filings can be separated from the mixture of iron fillings and sawdust.

Detailed explanation-2: -Iron filings are attracted by a magnet. So they are removed by magnetic separation. When a magnet is moved in this mixture, iron filings cling to the magnet and get separated.

Detailed explanation-3: -Strong magnets are used to separate the magnetic materials. The mixture of iron filling sand and iodine can be very well separated using magnetic separation because as we know iron is a magnetic material and will be attracted by magnet The mixture of iodine and salt are not attracted by magnet.

Detailed explanation-4: -Mixtures containing substances that are attracted by magnets can be separated using a magnet. We can separate iron from a mixture of sand and iron, as only the iron is attracted to the magnet.

Detailed explanation-5: -Let candle wax drip onto a piece of paper. Knead the wax while still warm. When you press the wax onto the magnet, the filings stick to the wax. Repeat step 1 to 3 until all filings have been removed. As a final step, you could use a tissue/rag to clean the wax off the magnet.
