What reading level is The Electro Platers Handbook a Practical Manual for Amateurs And Students in E book?
To quickly assess the difficulty of the text, read a short excerpt:
This armature was constructed to run at a high speed between the poles of a powerful steel magnet. The cur- rent thus produced, was led to the wire coils which sur- rounded a much larger cast-iron electro magnet. The polar extremities, or " pole pieces, " of this electro magnet, were made very massive, and a tunnel bored out between them, in which a second much longer cylindrical arma- ture was caused to rotate. This second armature was similar in general construction to the first, but very muc...h larger. The wire also with which it was wound was 1 Also known as the "old Siemens armature, " or "H girder armature. " DYNAMO-ELECTRIC PLATING MACHINES. 49 very much stouter, so as to present less resistance, thereby insuring a larger current. Since this machine was separately excited (i. E. , the magnetism of the larger field magnets was dependent on the separate current produced by the smaller dynamo) it was not subject to "reversal"; but owing to the fact of the armatures being both solid, which favours the gene- ration of Foucault or " eddy " currents in the iron, the armatures soon became very hot, so that, unless special devices were made use of to keep the rise of temperature within bounds, the covering of the wire of the armature coils was soon charred, and the insulation broken down.
