About this book
This handbook assumes a boy with few tools and little skill, and gives plain directions for making simple apparatus for elementary electricity experiments. Thomas M. St. John, a metallurgical engineer who also wrote Fun With Electricity and Fun With Magnetism, builds it from twenty-one chapters.
They run from cells, batteries and switches to magnets, induction coils, galvanometers, telegraph keys and sounders, electric bells and motors, and close with tools and materials. This is the eighth edition, and most of the illustrations were drawn from apparatus built by young boys.
