Excerpt from The Electromagnet
This book is a new and revised edition of "The Electromagnet" by Townsend Wolcott, A. E. Kennelly, and Richard Varley.
The author has endeavored to give the facts connectedly, so that the reader may easily follow the reasoning without referring to different parts of the book, with the exception of the tables, which are placed in the Appendix for convenience.
Much of the data, especially that concerning windings, has been obtained from actual practice.
As the economy and efficiency of an electromagnet depend largely on the proper design and calculation of the winding, particular attention has been paid to that detail.
Acknowledgments are due to R. Varley, W. J. Varley, A. D. Scott, J. M. Knox, and W. H. Balke for data and assistance.
