What reading level is The Telephone; Outlines of the Development of Transmitters And Receivers book?
To quickly assess the difficulty of the text, read a short excerpt:
IV.
Magnetic Phantoms.
Showing change in direction of lines of force, with motion of diaphragm.
The Telephone. 57 much less than that shown in these figures, it must be of the same character, the change in the direction of the lines closely following the motion of the dia- phragm. It should be noted, however, that these illustrations show the change in direction only, and not the change in the magnitude of the force.
When the magneto telephone is used as a receiver, the opposite action takes pl...ace. The strength of field changes in accordance with the variation in the current through the coil, producing a varying pull upon the diaphragm and thus converting the current waves, by means of the vibrations of the diaphragm, into air vibrations.
In order, therefore, to make the instrument as powerful as possible, the diaphragm must be so placed in the field, and the strength of the magnet must be such, that a given motion of the diaphragm will produce a maximum change in the distribution of the magnetic force, when used as a transmitter ; or so that, when used as a receiver, the variation in the current in the coil shall cause a maximum rela- tive change in pull upon the diaphragm.
