In 1821, Michael Faraday discovered that when a current carrying conductor is placed in a magnetic field, a mechanical force is exerted on it, except when it is placed parallel to the magnetic field.
This apparatus is used to demonstrate the force acting on a current carrying conductor in a magnetic field.
The apparatus comprises of a strong U-shaped magnet and a pair of brass rails with 4 mm socket terminals.
A brass axle with plastic discs is free to roll along the rails and completes the electrical contact between them.
When the axle is placed on the rails between the poles of the magnets, and the power supply unit is connected, the axle is repelled and rolls along the rails away from the center of the magnetic field.
This apparatus also helps students to practically understand J.A. Flemings left hand rule, which is used to determine the direction of force exerted on a current carrying wire in a magnetic field.
