Current Balance

Return to Magnetic Fields and Forces

Description:

For precise force measurement or for qualitatively showing the magnetic interaction of a current flowing in parallel wires. Parallel or anti-parallel currents can be set up and show when the parallel conducting rods attract or repel.. A laser bouncing off of a mirror onto a wall shows very small movements of the upper rod and magnetic dampening helps to limit oscillations. Note the wire connections in the attached photos and video,
