Book excerpt: Excerpt from The Theory, Design and Construction of Induction Coils Although the induction coil is one of the oldest forms of electrical apparatus, comparatively little progress has been made toward rendering its design an exact science. There are several reasons for this lack of progress, the most important of which are the following: The limited field of application, the method of rating by length of secondary spark, erroneous assumptions in the mathematical treatment of the theory, non-uniform performance of interrupters, and lack of instruments suitable for experimental study of the performance. The field of application has within the past few years spread from the laboratory and lecture room to medicine, radiology, wireless telegraphy, gas-engine ignition, etc., so that to-day the induction coil is as much a commercial machine as is the electric motor. The constantly growing commercial importance of this type of apparatus and the lack of an exact and definite treatment of its theory and performance, determined the writer to undertake the translation of H. Armagnat's most excellent work. In this work the author has recognized the extreme importance of the interrupter, and has devoted a generous portion of the work to the treatment of the theory, construction and operation of the various types now used. It is well known that the design of induction coils is almost entirely empirical, due to the lack of exact knowledge upon which a practical working theory can be based. H. Armagnat has done much toward clearing up the obscure points, and his work marks a decided advance toward the day when the induction coil will be calculated for a given service with the same assurance and accuracy.
