If some small pieces of iron are put near either of these magnets most of them will cluster around the ends of the magnet. This means that the magnetic effect is strongest at the ends. These are...

Who discovered the first magnet? In about 600 BC a Greek called Thales found a rock which attracted bits of iron to it. He named this rock ‘magnets’ after the town Magnets where it was found. The rock he found was an iron ore but other substances act in the same way. We call them magnets. Materials which are attracted to a magnet are said to be magnetic. Iron and...
