In general, like magnetic poles repel one another; unlike poles attract one another. Page 16 ... zero when the plane of the coil is at right angles to the direction of the lines of force, and therefore the induced electromotive force here is zero. Page 23 In an electromagnet, the strength of the magnetizing force, or magnetomotive force (abbreviated to MF), by which the lines of force are produced, is proportional to the strength of the current flowing through the field coil, or magnetizing coil, and to the number of complete turns through which the current flows. Page 13 Electricity is the name given to the cause of all electric phenomena. The exact nature of electricity is not known; but its effects, the laws governing its action, and the methods of controlling and using it are well understood. Electricity is neither a form of matter, as matter is generally understood, nor is it a form of energy, although energy is required to move it, and when in motion it is capable of doing work. Page 4 ... a certain amount of current at the proper moment, that is at the instant of the opening of the interrupter. The interrupter being closed the greater part of the time, allows the primary current to avail itself of the short path it offers. At the instant at which the greatest current intensity exists in the armature, the interrupter is opened mechanically so that the primary current has no choice but must take the path through the primary P of the induction coil. A certain amount of current is... Page 51 Rule. — Place thumb, forefinger, and middle finger of the left hand each at right angles to the other two; if the forefinger points in the direction of the lines of force, and the middle finger points in the direction towards which the current flows, then the thumb will point in the direction of movement imparted to the conductor.

Page 50 ... current induced in the secondary S of the induction coil is delivered to a distributing brush carrier D that rotates in the magneto at half the speed of the crank shaft of the engine. This brush carrier slides over insulated metal segments E — there being one for each cylinder. Each of these segments E connects with one of the terminal sockets that are connected by cable with the spark plugs as shown. At the instant of interruption of the primary current, the distributing brush is in contact... Page 52 ... be a magnet, or at least a magnet strong enough to hold the tack. When the circuit is again closed, the nail will again hold the tack. The coil of wire together with the electrically magnetized nail form what is known as an electromagnet. The wire winding is called the magnetizing, or exciting coil, and the iron or steel (nail in this case) is the core. One end of the nail will be a north magnetic pole and the other end a south magnetic pole. An electromagnet loses- nearly all its magnetism as... Page 19 When there are few lines of force through a magnet, a little increase in the magnetizing fdrce will produce a considerable increase in magnetism; but, if the magnetizing force is increased sufficiently, a point will be reached where but very little further increase of magnetism can be obtained. The magnet core is then nearly filled, or saturated, with magnetism. Complete saturation is never reached, but there is a limit beyond which it is impracticable to increase the magnetizing force further; dynamo-electric... Page 13 Other editions
