Key Features
Spherical conductor for charged-body demonstrations Shows attraction, repulsion and charge interaction Used with electrostatic generators, electroscopes and proof planes About This Product
Two charged spheres brought closer or moved apart show qualitatively how the force between charges changes with distance, the idea behind Coulomb’s law. The sphere is used with insulated supports and an electrostatic generator. Schools, colleges and institutes in Liberia, Saint Lucia, Mongolia, Côte d'Ivoire and Papua New Guinea can order the Coulomb’s sphere from Educational Instrument.
