Amp up your understanding of electricity and magnetism with dozens of do-it-yourself experiments.

Electricity Experiments You Can Do At Home is a hands-on guide that helps you master the principles of electrical currents and magnetism. Each of the book’s three sections–direct current, alternating current, and magnetism–begins with step-by-step instructions for setting up your lab for the experiments that follow. Using inexpensive, easy-to-find parts, the experiments progress from basic to more complex and will spark ideas and encourage inventiveness. Expect unexpected results when you experiment with:

  • Diode-based voltage reducer
  • Compass-based galvanometer
  • Photovoltaic illuminometer
  • Utility bulb saver
  • Ripple filter
  • Xener-diode voltage regulator
  • AC spectrum monitor
  • Ampere’s law with wire loop
  • AC electromagnet
  • Handheld wind turbine
  • And dozens more projects

Electricity experiments you can do at home helps you to:

  • Solve circuit problems in electricity
  • Build practical and interesting electrical and magnetic devices
  • Get ideas for science-fair projects
  • Prepare for advanced courses in electricity and electronics
  • Learn the basics of laboratory practice


This book will educate you, give you ideas, and provoke your curiosity. The experiments described here can serve as a “hands-on” supplement for any basic text on electricity. I designed these experiments for serious students and hobbyists. If you don’t have any prior experience with electrical circuits or components, I recommend that you read Electricity Demystified before you start here. If you want a deeper theoretical treatment of the subject, you can also read Teach Yourself Electricity and Electronics.

If you like to seek out mysteries in everyday things, then you’ll have fun with the experiments described in this book. Pure theory might seem tame, but the real world is wild! Some of these experiments will work out differently than you expect. Some, if not most, of your results will differ from mine. In a few scenarios, the results will likely surprise you as they surprised me. In a couple of cases, I could not at the time—and still cannot—explain why certain phenomena occurred.

As I compiled this book, I tried to use inexpensive, easy-to-find parts. I visited the local Radio Shack store many times, browsing their drawers full of components. Radio Shack maintains a Web site from which you can order items that you don’t see at their retail outlets. In the back of this book, you’ll find a list of alternative parts suppliers. Amateur radio clubs periodically hold gatherings or host conventions at which you can find exotic electrical and electronic components.
