It's rather lovely! Lasttime I saw something like that it was described as an "Undulator".

I'd get it working, and - as mentioned above - make up something that can send Morse to it as a demonstration [I'd suggest one of the cheap electronic 'voice recorder' things available for a few pounds, used to record tones, then on playback a diode to convert the tones to DC which then drives a switching transistor to drive the coil].
