The Study of Elementary Electricity and Magnetism by Experiment: Containing Two Hundred Experiments Performed with Simple, Home-made Apparatus

"The Study of Elementary Electricity and Magnetism by Experiment" by Thomas M. St. John is a scientific publication written in the early 20th century. This instructional text serves as a comprehensive guide for amateurs and students, focusing on a systematic approach to conducting practical experiments related to electricity and magnetism using simple, home-made apparatus. The book's goal is to provide readers with hands-on experience in understanding fundamental concepts of electricity and magnetism through a series of two hundred experiments. The opening of the book outlines its purpose and structure, addressing the intended audience while emphasizing the necessity for readers to approach the experiments in a sequential manner. St. John stresses the importance of understanding each step of the experiments thoroughly before moving on to subsequent ones. He also indicates that the chosen apparatus for the experiments will be both basic and affordable, encouraging students to create their own equipment where possible. This approach not only educates but also fosters a sense of creativity and engagement with the experiments presented throughout the work, setting a solid foundation for readers to explore the principles of electricity and magnetism effectively.
