Silk Cloth Square for Static Demonstrations, 12 x 12" Material_Bristle sized for low-current circuit work

sized for low-current circuit work below the 1A range where finer resolution matters more than full-scale capacity

Alnico U-shape with 45mm pole spacing concentrates the field across a small gap

supporting a 1

supplying an inert electrode that conducts current without contributing its own ions to the cell reaction

polished with ground edges for image-formation experiments in introductory optics

Silk Cloth Square for Static Demonstrations, 12 x 12" Material_Bristle sized for low-current circuit workUsed to draw electrons from glass and ebonite rods during rubbing, this silk square gives friction rods a strong positive charge for triboelectric and electrostatic demonstrations.
