Abstract
THE experiment described by Maxwell1 in which magnets are placed on a tray free to rotate about a long straight wire carrying a heavy current is well known. The present variant of this experiment is intented for demonstration purposes, and provides for (a) a proof that the forces acting on the magnets are amply large enough to cause a violent movement of the tray if the resulting moment was not in fact zero ; (b) the use of current-carrying coils as well as magnets.
