A thin steel rod (called vibrator) is clamped at one end and passes through a small solenoid. The rod is slightly flattened at the free end and a hole is drilled in it so that string can be tied to the rod through this hole.
The solenoid is connected to AC mains through a suitable lamp on the base board and a steel rod passes between them. The thin rod is magnetised longitudinally. The solenoid and a horse shoe shaped magnet causes it to vibrate with the frequency of AC supply. The length of the vibrator is adjusted until its natural frequency corresponds with that of supply. The whole unit is mounted on a polished wooden base.Complete with pulley, pan and cord.
