Designed as a hands-on guide for labs, the hobbyist, or for the industry professional, this book covers instructions and methods for doing experiments with currents and magnetism. It includes 49 separate experiments on electricity, magnetism, currents, voltage, generators, transformers, relays, alternators, resistance, gaps, and more. Each experiment covers: the object, method, result, and questions with answers on the experiment under discussion. A separate chapter at the end of the book has over 175 questions with answers to test your knowledge of electricity and electronics.
