generator is one of many variants of a frictional electrical machine used in the second half of the 18 th century. It became standard equipment for the systematic research on the then new found phenomenon [...] rotating disk passing on the electrical charges to the conductor. We use the instrument in two versions, for historical research, a glass disc is placed into the instrument. However, for educational purposes, a disc of acrylic glass is used for reasons of practicability and safety. further reading Hackmann, W. D. (1978).

precursor to the tangent galvanometer is the tangent bussole, which used a ring of plain copper instead of the induction coils. The tangent galvanometer in our HistoLab is labelled "Philip Harris Ltd.
