A New Alternating Current Motor - Editorial

Our issue of the 25th of May contained an abstract of a Paper by Prof. Galileo Ferraris describing a method of producing a revolving resultant magnetic field by means of a pair of coils with their axes at right angles, and traversed by alternating currents, and we drew attention to the possibility that the principle of this apparatus might be applied to the construction of an alternating-current motor. The Paper by Mr. Nikola Tesla, which appears in our columns this week, contains a description of such a motor, founded on exactly the same principle.
