Jumping Wire

This visually illustrates the interaction between a current-carrying conductor and a magnetic field. In this setup, a straight wire is placed in the magnetic field of a horseshoe magnet. When an electrical current flows through the wire, it experiences a force perpendicular to both the magnetic field and the direction of the current, as described by the right-hand rule (or Fleming’s left-hand rule for motion). This force, known as the Lorentz force, causes the wire to "jump" or move when the power supply connected to the battery of the wire is turned on. This experiment provides a way to demonstrate the relationship between electricity and magnetism and shows how forces on a conductor are influenced by electromagnetic fields.
