Material
DescriptionThe instrument has a black-painted, spherical iron body sitting on a rectangular metal base with a screw at each end for attachment to a surface. There is a depressed band that runs around the circumference of the body, parallel to the long edges of the base. There is a round, textured screw at the outermost point on both sides of the depressed band.
A metal axle runs through the entire device, emerging on both sides. On one side of the device, the axle ends with a two-tiered cylindrical extension. The bigger tier, closest to the body, is brown metal and has an adjustment screw sticking out to the side. The smaller diameter tier is darker and textured. On the opposite face of the body, the axle hosts a tightly wound coil of copper-colored wire with a vertical brass frame screwed to the black body on either side. There is a brass knob capping the axle on this end. On either side of the coil, there is a perpendicular black cylinder with a brass cap.
There is a slit, parallel to the long edges of the base platform, on the surface of the body beneath the coil. Two (or possibly one continuous) thick insulated wires emerge from the slit and attach to the brass caps on the black cylinders.
