Magnets

Whether you know it or not, there are magnets hidden everywhere - in hairdryers, in telephones, in compasses. This exciting book will describe how magnets make engines work, how they help people find their way, and even how magnets can be switched on and off. 10 practical projects - such as making a magnet out of a paper-clip and turning a bowl of water and needle into a compass - together with explanatory artworks enable kids to learn more about magnets in an informative but entertaining way. Ideal for home or school use.
