• 12:22, 20 April 2022 Physdemo talk contribs created page Current Balance (Created page with "{{NewDemo|subject=Electricity and Magnetism|topic=Magnetic Fields and Forces|file1=Current Balance.gif}} For precise mass measurement or for showing the interaction of current in parallel wires. Parallel or anti-parallel currents can be set up in the two parallel rods. A laser bouncing off of a mirror onto a wall shows very small movements of the upper rod and magnetic dampening helps to limit oscillation.
