Current Balance In a current balance, a straight wire segment is placed between the poles of a magnet so that it experiences a magnetic force when current flows. if the magnetic force is downward, the balance reading increases. if the current is reversed, the magnetic force reverses and the balance reading decreases. A quick demo of how i use the current balance to determine the mass of a staple see physicshigh for all my videos and other resources. if you like this video, please press the like.
Wigton Physics Current Balance When a magnet pushes a wire up, the wire must push the magnet down with the exact same force. by placing the magnets on a sensitive digital scale, we can “weigh” this magnetic push. use the “current balance lab” below to perform this classic physics experiment virtually. In this experiment you will verify that the force between two wires is proportional to the product of the currents, and estimate the proportionality constant involved. Lab manual for a current balance experiment. measure magnetic forces exerted by electrical currents. physics, electromagnetism, college level. In this experiment you will use a current balance in which the upper conductor is free to pivot on knife edges. the upper conductor is balanced so that the wires are a small distance apart.

In this experiment you will use a current balance in which the upper conductor is free to pivot on knife edges. the upper conductor is balanced so that the wires are a small distance apart. The current balance is used to measure the force of repulsion between identical, oppositely directed, currents in parallel conductors. this shows a direct link between the mechanical forces of newton and the electromagnetic forces of ampere and maxwell. In this experiment, a current carrying wire will be placed between the two poles of a magnet. when cur rent is flowed perpendicular to the magnetic field, the wire and the magnet will either push or pull on each other in the vertical direction. In a current balance, the conductors form part of an arm of a sensitive balance and the force between them, when they carry a current, is counterbalanced by a weight m added to the other arm. When a current passes through a coil of wire, the coil of wire behaves like a magnet. the magnet attached to the straw is then attracted towards the coil, and the straw becomes tilted. the force between the two magnets can then be balanced by putting a counterweight on the other end of the straw.
