About This Book
A practical manual for young experimenters introduces fundamental electricity and magnetism, explains measuring units and common apparatus, and gives step-by-step plans for building cells, motors, dynamos, induction coils, telegraph and telephone devices, transformers, wireless receivers and a miniature electric railway. Principles are explained alongside clear construction details and safety cautions so readers can both understand everyday electrical phenomena and assemble working projects from accessible materials. Illustrations and progressive chapters move from simple magnetism and static machines to household lighting and miscellaneous apparatus, emphasizing hands-on learning and problem solving.
