Laplace Force Demonstration

Product Code: SF-7261


The Laplace Force Demonstration demonstrates the forces on a current-carrying wire in a magnetic field.

Note: This is just the apparatus without the Horseshoe Magnet. To purchase the complete system including the magnet, see the Laplace Force Demo with Magnet (SF-7279).

When the conducting rod is placed on the rails and a current (maximum 10 A) runs through the rails, the rod will be affected by a force, making it roll perpendicular to the magnetic field along the rails.

The apparatus consists of a pair of rails with 4 mm diameter terminals. The conductor consists of a bar with plastic discs that is placed across the rails.
