Spherical Conductor for Electrostatics

This aluminium sphere measures 8 cm in diameter and is fitted with an insulating plastic rod mounted on a base. The combination of a conductive metal sphere with an insulating handle makes it suitable for electrostatic experiments and demonstrations. The insulating rod allows the sphere to be charged and manipulated without discharging through the user's hand, making it a useful component for physics classroom demonstrations involving static electricity, charge distribution, and electrostatic induction.
