Electromagnetic Vibrator (Original Model)

The original Frederiksen Scientific electromagnetic vibrator has a quality coil and precisely centred guide for a wide frequency range and high movement amplitude. It is protected by an electrical fuse and a lock for the moving parts, and is supplied with a string holder, clamping pin and spare fuse. Use it with a function generator to demonstrate mechanical oscillations, waves on a string, spring resonance and Chladni patterns.
