Page after page, this title proves that the power of attraction is undeniable. Readers move beyond a simple fascination with the power of magnets to a clear understanding of the science behind magnetics. Natural magnets, Earth's magnetic field, and the ties between electricity and magnetics are all featured, in addition to the creation and use of magnets in commercial and everyday applications. Information about the life and work of physicist Joseph Henry, a leading electromagnetics pioneer, and a timeline of important dates in the field are also included.

Modern life makes extensive use of electronics. On a daily basis, we use smartphones, computers, and TVs in the home and robots in industry and commerce. This title outlines the development of electronics, from early vacuum tubes to todays microchips. It explains how semiconductors work at the atomic level and how they are made into solid-state devices essential for the Internet and other applications. A biographical chapter on J. J. Thomson, who discovered the electron (the key to electronics), rounds out the text. Science projects readers can try at home illustrate principles of physics.
