Book 2 in which a scarecrow gives Millie a brilliant idea about magnets is a humorous introduction to magnetism based on the orientation of electron spins. In this adventure, Millie wants to know what it is like to be an electron; she learns about magnetic fields, attractive and repulsive forces, and the difference between magnetic and non-magnetic materials. Children love this book. Here are some of their comments:

I was more involved and used my brain a little more than with Book 1. Mia, 10
