Force on a Conductor Balance
Force on a conductor balance – It is used to demonstrate that when a current is passed through a conductor in a magnetic field, it is subjected to a force of attraction or repulsion depending upon the direction of current in it.
Product Information
Force on a Conductor Balance is a classic physics laboratory apparatus used to experimentally demonstrate the magnetic force experienced by a current-carrying conductor placed in a magnetic field.
Features:-
- Educational Use: Ideal for demonstrating the interaction between electric current and magnetic fields in accordance with Fleming’s Left-Hand Rule.
- Durable Construction: Designed with a robust base, precision balance arm, and high-quality conductor for accurate results.
- Adjustable Setup: Allows easy variation of current, magnetic field strength, and conductor length to observe their effect on force.
- Clear Readings: Sensitive balance mechanism ensures precise measurement of small forces.
- Safe Operation: Fitted with insulated connections for secure handling during experiments.

A balance beam is supported by the pillars on two bearings, which form the fulcrum. Two screwed masses are provided in the beam system, one moving vertically for the adjustment of sensitivity and the other moving horizontally for the adjustment of the equilibrium position, when no current is flowing. Scale marked 0 to 75 x 1mm, rider of 1 gm weight.
Working Principle:-
When an electric current passes through the horizontal conductor placed in the magnetic field of a permanent magnet, it experiences a force perpendicular to both the current and the field. The magnitude of the force can be measured using the balance and compared with theoretical predictions, reinforcing fundamental concepts in electromagnetism.
