Magnetic and non-magnetic substances

Apart from iron, the other common elements which are attracted strongly by a magnet are cobalt and nickel. These, together with certain strongly magnetic alloys are described as ferromagnetic. Substances such as copper, brass, wood, and glass are not attracted by a magnet, and are commonly described as non-magnetic.

Nevertheless, experiments with very powerful magnets have shown that even the so called non-magnetic substances have very feeble magnetic properties. We shall have something to say about these in the next chapter.
