Wimshurst Machine, Superior
This traditional electrostatic charge generator consists of two parallel transparent discs supported on rigid uprights. Each disc has a number of radial aluminium segments and are driven in opposite directions by hand wheel and belt. The electrostatic charge on aluminium segments is collected by combs mounted on either end of the discs and stored in the two leyden jars. When the potential difference between the jars is sufficiently high. A spark will flow between the adjustable discharging spheres.

Newton’s/Coulomb’s Law Demonstration
Study the concepts of Newton′s and Coulomb′s laws with this apparatus. This apparatus can be used to demonstrate repulsion, attraction of charged bodies and provides the ability to measure the angle between the 2 strings and thus the force between the two charged spheres. The charge can be provided by a Wimshurst machine or a Van de Graff generator or by simply rubbing a plastic rule with on a duster. Includes manual.

Coulomb’s Law Apparatus
Coulomb’s Law
Study the force between two electric charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
Mathematical Representation
F: electrostatic force
k: Coulomb’s constant
Q1, Q2: charges of the two objects
