Description

Extremely rare gas lighter with Nobili’s electromagnetic spark ignition.

This rare instrument has inside a gasometer that obtains hydrogen from a reaction with an element of zinc immersed in sulfuric acid. The hydrogen passes outside to a central tap , here the gas flow is ignited by a spark caused by an electric coil and a large electromagnet. The inflamed hydrogen ignites a small light placed on the side.

The scientist Leopoldo Nobili created the so-called “sparkling magnet” in the 1830s ,  noting that an electric winding in contact with a magnet emits sparks when the coil is detached from the magnet itself and refuting the phenomenon of electromagnetic induction discovered by faraday.

The wooden box   have a large magnet connected to the coil which detaches the large central coil by means of a lever .

Very rare instrument containing an important phase of research on the effects of electromagnetism, complete and in excellent condition, not signed but certainly produced in Italy.

at the end of the photos you can see examples of sparkling magnets preserved in various Italian museums
