What reading level is The Elementary Principles of Wireless Telegraphy book?
To quickly assess the difficulty of the text, read a short excerpt:
When the two coils are remotely separated, as FIG. 58.
shown in Fig. 58, so that none of the lines of force in- duced by A pass through B, and vice versa, then the total inductance of the two coils will be the same as in the case illustrated in Fig. 50, namely 16. But when the two coils are placed closer to one another, as shown in Fig. 59, so that two lines produced by each coil thread the other, then these two lines - -^--, . , ^. . , being in the opposite direction will neutralise two of the... lines induced by that coil, so that in this case a current of one ampere will have the effect of causing only two lines of force to thread each coil, and, therefore, the total inductance of the two coils together will then be (2x2) + (2x2) 8.
386. Now the dill'ercnce between this total inductance and the total inductance of the tv. O coils when a great distance apart, as shown in Fig. 58, that is to say 8 - 16, FIG.
104 WIRELESS TELEGRAPHY will again represent the mutual inductance of the two coils, which it will be seen is the same value, but opposite in sign to the value of the mutual inductance, when the two magnetic fields were in the same direction.
