Image description edit

German text:

Wirkung starker elektromagnetischer felder 

Die grobe Spule ist auf die grundfrequenz des Oszillator (50,000 Perioden) abgestimmt. 
Die beiden größeren Vertikalspulen auf die doppelte und die übrigen auf vielfache Grundfrequenz. 
Eine kleine, auf 26 fache Grundfrequenz abgestimmte Spule wurde ebenfalls stark erregt.

Translation:

Effect of strong electromagnetic fields

The large coil is tuned to the fundamental frequency of the oscillator (50kHz),
the two larger coils to the second and higher harmonics. A small coil, tuned to
26 times the fundamental, becomes strongly excited.
