Toestel op een elektromagneet voor de mechanische werking van inductiestromen before 1867

This photograph, taken before 1867, captures a device for generating electricity, known as a "Toestel op een elektromagneet voor de mechanische werking van inductiestromen" (Device on an electromagnet for the mechanical operation of induction currents). Created by F.W. Funckler, this small device, measuring 59mm in height and 52mm in width, represents a significant step in the development of electromagnetism. It was likely part of a larger collection of scientific equipment or a catalog for educational purposes. The photograph's stark contrast and focus on the central device emphasize its importance and highlight the intricate workings of this early technological marvel.
