Measurement of forces between two parallel conducting cylinders

Abstract

We describe the experimental arrangement and method to measure the force between pairs of parallel conducting cylinders at different separations and with fixed potential differences. The results of the measurement for diverse values of the geometrical and electrical parameters are reported. The measured forces are compared with their values evaluated on the basis of Ref. 1, finding a good agreement for cylinders of the same length, and recognizing the edge effects for cylinders of different lengths.
