512 Spin Type Electroscope

This simple device can even detect a charged friction rod. It consists of a metal arm with a hub at its center and oppositely directed points on each end. The arm pivots on a needle bearing on an insulated stand. When a charged rod is brought close to the points, the electroscope begins to spin. In stronger fields, the speed increases. The spinning arms are 15cm in diameter.
