| APPARATUS TO SHOW FORCE ON A CONDUCTOR IN MAGNETIC FIELD
(0302) |
| Demonstrates the force experienced by a current carrying conductor when placed in magnetic field. Comprises a pair of brass rails mounted parallel to each other on a metal base, each rail having 4mm socket terminal at their one end for electrical connection. A strong U-shaped magnet fixed on the base such that its one pole is vertically above the rails and other below it and is positioned between the two rails. A brass axle with plastic discs at its both ends is free to roll along the rails and completes the electrical connection between them. When the current is made to flow through the rails with the axle placed on the rails between the poles of the magnet, the axle is repelled and rolls along the rails away from the center of the magnetic field. |
