"Magnetic hysteresis in armature core. Unlike poles are induced in the core opposte the poles of the field magnet. Since on account of the rotation of the core the induced poles are reversed a thousand or more times a minute, considerable energy is required to change the positions of the molecules f the iron for each reversal, resulting in the generation of heat at the expense of a portion of the energy required to drive the armature." -Hawkins, 1917

"Illustrating the effects of introducing an iron core into a solenoid. In the upper firgure, the air space or 'air core' surrounded by the solenoid offers considerable resistance to the passage of magnetic lines, allowing only a small number to pass through. If a pieve of iron be introduced, as in the lower figure, the number of lines will be greatly increased." -Hawkins, 1917
