Editorial Reviews

Children's Literature - Laura Ruttig
Part of the "Scientific American" series, this interesting title focuses on how magnets have literally changed the world. Tomecek begins with a history of magnets, from the early discovery of Gilbert in the sixteenth century that magnets have poles, to Volta's creation of a battery, followed by Sturgeon's creation of the first electromagnet in 1823. From these early developments, there came a staggering array of inventions from Edison, Westinghouse, Tesla, and others, which led to electric engines in factories and ultimately the rise of the Industrial Revolution. The telegraph and Morse Code, the telephone, Marconi's invention of the wireless radio, radar, the microwave, x-rays—all came from the scientific understanding of magnets and electricity. Tomecek also gives a clear explanation on how magnets work in modern scientific terms and how they can be used to create electricity. With so much to cover, he limits his writing to an intriguing overview of the history of electromagnetism, which may leave readers curious to explore the further resources listed at the back of the book.
