魯姆考夫線軸 (3) - 木, 銅, 黃銅 - 20世紀初
Devices used in physics laboratories for electrical current experiments. They are induction coils (also known as the Ruhmkorff coil) which, starting from a low-voltage direct current source, produce high voltage pulses. The devices are three of which the oldest, probably from the late 1800s, is a real collector's item. The dimensions shown refer to this piece.
