Magnets, Motors, and Generators: Magnets and Spinning Shafts

We take motors and generators for granted because they are so successful and reliable. Thank magnetic fields. Magnetic fields have completely changed and improved our way of life, compared to just 200 years ago. We have electric motors everywhere, in refrigerators, fans, elevators, cars, computers, and toys. 

This book shows that magnet and motor experiments have real uses and applications. It should not be hard for the reader to realize how important motors and generators are to modern life styles (starting your car, playing DVDs, electric tools, dishwashers, air conditioners, elevators, household water pressure). 

¿Two audiences were in mind when writing this book.  One is a young person who is interested in how things work, probably with the help of a parent.   Another is two college students, probably history or business majors, discussing how things work over a beer.  These two business majors will probably be the boss of the engineer young person when they all grow up.
