Electric pendulum 133-140 1 unit

Two small balls coated with a conductive material are hung from the top end, and the movement of these balls allows for experiments in the repulsion and attraction caused by electrostatic charge. You can also experiment with attraction due to electrostatic induction and repulsion after a charge is transferred when small balls come into contact. There are two fulcrums so that the distance between the balls can be adjusted. Product code: 133-140
