Coulomb's Law Demonstrator - Physics Apparatus

Nvis 6012 coulomb's law demonstrator is an
important setup to understand the conceptual aspect
of coulomb's law. Coulomb's law states that the force
between two electrical charges is proportional to the
product of the charges, and inversely proportional to
the square of the distance between them. Coulombic
force is one of the principle force involved in atomic
reactions. Coulomb's law is applicable for electric field, gravitational field
and magnetic field. In this product magnetic force is used for coulomb's
law demonstration. A pair of magnets of constant and equal pole strength
are mounted horizontally with varying distance. It allows the inverse
square law to be ver I f ied wi th reasonable accuracy.
A simple balance system is developed to measure force between two
magnets in end on position.
