    to e; + f to h. Sound similar to last. May have been slightly fainter (See Fig.1)
  1. Circuit g-dM'b-cMd-eM2f-h. The two coils MM', being connected as in a Morse Sounder. Sound decided -- similar to that mentioned in experiment 10.
  2. Circuit g-aM'b-dMc-eM2f-h. The coils MM' opposing each other's actions.
    Sound exceedingly faint ­ only half as loud as last.
  3. Circuit aM'b-cMd-eM2f-a. No battery. Sound faint. similar to that in exp. 3.
  4. Circuit aM'b-cMd-cM2f-a. No battery. Sound very faint similar to that in exp.6.
  5. Effect of battery power upon the sound. Sound audible at S1 when no battery was used. Call equal to 10 in intensity ­ Upon introducing Battery between f + c the intensity of the sound was increased.
