THIS book is intended for engineering students and for electrical engineers who are engaged in transmission and design. All the matters discussed are directly useful to engineers. Since Faraday and Henry discovered magnetic induction, the theory of the transformer has strongly attracted mathematical scientific men. In our opinion there has been very little true theoretical progress since Maxwell gave the theory of the air core transformer in 1865. Fleming has expanded this theory and given it in a form which can be easily understood. When, however, attempts are made to take hysteresis and eddy currents into account, we have to fall back on approximate formulæ, and in most cases we are ignorant of their limitations.

The Principles of Electric Power Transmission by Alternating Currents.
