The diagramsare from Lewis Jones book. One pole of the battery INDUCTION COIL 85 is connected to the coil at A. The current then passesby the adjusting screw B, the vibrator H, and the sup-port K, to a magnet D, which actuates the contact-. Arrangement of wires of an induction coil. breaker. After traversing this the circuit gives off a branchto the binding screw P, and is continued to the primarycoil E E, the return wire from which again gives off a branch Fig. 25
