1. The button at the top (K) is closed. 2. Current flows through the solenoid (E). This produces a magnetic field. 3. This pulls the magnet (A) toward the solenoid. This bar hits the bell, creating a dinging noise. 4. When A goes up, it pulls away from T and hits B, the bell. This movement disconnects A from T and disconnects the circuit (the current no longer can flow in a full circle.) 5. Since the circuit is disconnected, the current flowing through the solenoid is stopped, and the magnetic field retracts. 6. Since the magnetic field is no longer there, A is no longer attracted to the solenoid, so A falls back down. 7. When A falls, it reconnects to T, and the circuit is complete again. The process restarts with steps 2-7 until K is no longer pressed.

This circuit image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.
It is recommended to name the SVG file "Electric Bell animation.svg" - then the template Vector version available (or Vva) does not need the new image name parameter.
