Electrical Experiments: A Manual of Instructive Amusement. E-book. Formato PDF. This book is written in response to suggestions received from correspondents, and hints given in letters sent to the Editor of Work, that I should write a book showing how Induction Coils and other electrical apparatus can be used for instructive amusement. My correspondents state that a large number of idle hours hang wearily on the hands of youths during the long winter evenings in country villages, which could be spent in profitable amusement if they only knew how to use easily-made electrical apparatus.
