About the Author

Sally M. Walker has been a children's book writer for over 20 years. Most of her books are nonfiction and present various science topics to young readers. Fossil Fish Found Alive is the story of the hunt for the elusive fish called the coelacanth. Sally also enjoys combining science investigation with historical topics. Her book Secrets of a Civil War Submarine, which won the 2006 Robert F. Sibert Medal, tells about the history, loss, and re-discovery of the first submarine to sink an enemy ship in battle. Written in Bone: Buried Lives of Jamestown and Colonial Maryland takes readers on archaeological expeditions, where the forensic analysis of colonial settlers' bones helps us to understand their lives. Sally especially enjoys writing narrative nonfiction that captures the reader's attention with a true story.

You may not realize it, but there are magnets all around you. There are some that you can see while others are "hidden inside earbuds, telephones, and computers." Most of us have magnets on our refrigerators that hold up pictures, some that have advertising on them, or simple word magnets you can create sentences with. Every magnet has a force, or magnetic push or pull. The magnetic forces inside machinery help you to listen to music, enable you to work or play on your computer, and talk to friends on the telephone. The magnetic force begins with the simple atom. Even you are made of of atoms and in this book you will learn about the parts of an atom and how they work together to a magnetic force. You will explore protons, neutrons, and electrons, the "smaller particles" that comprise an atom. Naturally when you begin to take a close look at magnets and their magnetic force you will quickly realize that not all magnets are created equal. Some of them carry a very weak force while others are quite strong. You'll also learn from an experiment in this book that some "magnets are temporary magnets" while others are permanent. Not all materials are magnetic and you can find out which are by touching a magnet to them. If the magnet does not stick to the material it's obvious that there is no magnetic attraction. But you will find out that "magnets stick to any magnetic material." There are several interesting experiments outlined in this book to help you explore the wonders of magnetism. You will also learn about magnetic fields, the two parts or poles of a magnet, how magnets" can affect the magnetic field of another magnet, Earth's magnetic field, the different types of magnets, and you'll learn many other interesting things about magnets and magnetism. This is an excellent book for the young student to explore magnetism and its basic physics concepts. One of the strongest points of this book are the numerous experiments that young students can explore and learn from as they work their way through the book. One of the first concepts, the orbit of an electron, can be easily understood by a simple demonstration of one child seated and another one walking and alternately spinning in place around him or her. There are numerous informative sidebars that help emphasize a concept being discussed. For example, one diagrams two paper clips (temporary magnets). The young student can visually interpret the concept as well as read an explanation of how they become temporary magnets. In the back of the book is an index, a glossary, and additional recommended book and website resources to explore. This book courtesy of the publisher.
