Elektrische Spule mit Hochfrequenzgenerator und Kondensator betrieben

we operate the coil from a specially constructed alternator, capable of giving many thousands of reversals of current per second, or, by disruptively discharging a capacitor across the primary, we create a vibration in the secondary circuit of a frequency of many hundreds of thousands, or millions, if we so wish; and by using either of these means we enter a field as yet unexplored.
