Concept: Two coils, a primary coil with few turns of thick wires wrapped around a soft iron core, and a secondary coil with many turns of thin wire wrapped outside the primary coil. The two coils are insulated from one another. Current is induced in the secondary coil when current in the primary coil changes. A battery supplies direct current (DC). Thus, the secondary coil would only have current induced when the primary coil was first turned on, or just after it turned off. With steady DC current in the primary coil, there is no induced current in the secondary coil. The vibrator functions as an automatic switch, rapidly turning the primary coil current on and off. Here's how it works: when the momentary-contact switch is closed, current from the battery flows through the primary coil; this creates a magnetic field around the core, which both induces current in the secondary coil, and attracts the hammer of the vibrator; as the hammer moves toward the core, it's electrical contacts are opened, cutting off the current to the primary coil; this reverses the induced current in the secondary coil, and allows the hammer to spring back; when the electrical contacts on the hammer close again, the cycle repeats. The action of the interrupter creates high-voltage pulses of dc current in the secondary coil. The voltage is high because the number of turns in the secondary coil is much larger than the number of turns in the primary coil.
