Présentation de l'éditeur

May 23rd, 1825, by William Sturgeon, on the occasion of reading a paper which is to be found in the volume of the Transactions of the Society of Arts for that year. For this invention we may rightfully claim the very highest place. Electrical engineering embraces many branches, but most of these are concerned with electromagnets. The dynamo for generating electric currents, the motor for transforming their energy back into work, the arc lamp, the electric bell, the telephone, the recent electromagnet machinery for coal mining and for the separation of ore, and many other electro-mechanical contrivances, come within the purview of the electrical engineer. In every one of these, and in many more of the useful applications of electricity, the central organ is an electromagnet. By means of this simple and familiar contrivance an iron core surrounded by a copper wire coil mechanical actions are produced at will, at a distance, under control, by the agency of electric currents. These mechanical actions are known to vary with the mass, form, and quality of the iron core, the quantity and disposition of the copper wire wound upon it, the quantity of electric current circulating around it, the form, quality, and distance of the iron armature upon which it acts. But the laws which govern the mechanical action in relation to these various matters are by no means well known, and, indeed, several of them have long been a matter of dispute. Gradually, however, that which has been vague and indeterminate becomes clear and precise.
