Excerpt from Dynamos and Electric Motors: How to Make and Run Them With Numerous Engravings and Diagrams

There are many who believe that electricity actually runs, or flows, from one end of a wire or conductor to the other, in a certain direction, when the ends are connected to a battery or dynamo. For instance, in the case of a battery of primary cells, the current is always spoken of as coming from the carbon terminal, going through the external circuit, and returning to the zinc. This, in point of fact, is misleading for the expres sion is quite conventional, and it might easily have been expmd the other way, and would have made no difference whatever to electrical formula or laws. But when electricity came to be studied and advance was made in the science, it was mutually agreed to express the phenomenon in this way.

In a similar manner it was agreed to call one end of a magnet the north pole, and the other the south but in this case we are brought face to face with a paradox. It is this: either we have all along been giving our magnet ends wrong. Names, or else Franklin, and many others after him, have diligently been searching the Arctic Seas for the North Pole when it is the south all the time; for like poles repel each other, unlike poles attract. Perhaps it has been noticed that many writers are careful in calling the two ends of a magnet the north-seeking and south-seeking poles respectively.

Reseña del editor:

Handbook contains, in a form convenient for everyday use, a comprehensive digest of the information on How toM ake andR unS mall Dynamos andE lectric Motors, scattered over ten thousand columns of WORK, one of the weekly journals it is my fortune to Kedit and supplies concise information on the general g= principles of the subjects on which it treats. In preparing for publication in book form the mass of relevant matter contained in the volumes of WORK, Cmuch that was tautological in character had to be reg jected. The remainder necessarily had to be arranged anew, altered and largely re-written. From these Zcauses the contributions of many are so blended that the writings of individuals cannot be distinguished for acknowledgment. Readers who may desire additional information respecting special details of the matters dealt with in this Handbook, or instruction on kindred subjects, should address a question to WORK, so that it may be answered in the columns of that journal.
