How can we separate iron nails mixed with sand?

To separate iron nails mixed with sand, we can use a magnet. Since iron is a magnetic material, it will be attracted to the magnet, while the sand will remain behind. By moving the magnet over the mixture, the iron nails will stick to the magnet, and we can easily remove them from the sand. This is a simple and effective way to separate the two materials.
