Objective: Measurement of the force exerted on a current-carrying conductor located inside a magnetic field
The electric balance is based on André-Marie Ampères’ experiments on electric current. It measures the electro-dynamic force sometimes referred to as the Lorentz force on a current carrying conductor situated in a magnetic field using a balance. In this experiment the current conductor is suspended from a rigid suspension system and exerts the equal and opposite force on the permanent magnets as the electro-dynamic force generated by the magnetic field. The result is the apparent change in weight of the permanent magnets.
