Induktive Wirkung eines starken Oszillators

Drei Glühlampen befinden sich in einer quadratischen Windung von 50 Fuß (ca. 15 m) Seitenlänge, die sich vom durch den Oszillator erregten Primärkreis 100 Fuß (ca. 30 m) entfernt befindet. Die Windung enthält einen Kondensator und ist exakt auf die Frequenz des Oszillators abgestimmt.
