Magnets Push, Magnets Pull ~ David A. Adler

Magnets can be found in phones, stereos, vacuum cleaners, washing machines, televisions, and many other things.

It is believed that the core of the earth is an alloy of iron and nickel, which gives the earth its magnetic field. So the earth is a huge magnet.

If you tie a bar magnet to a piece of wood and place it in a bowl of water, it will slowly rotate and the north pole of the magnet will point to the north pole of the earth. There is a small bar magnet in the compass that works the same way so that the explorers can find the way.
