1. Description
Maxwell's wheel is used to demonstrate the conver-
sion of kinetic energy into potential energy and
vice versa.
The wheel is suspended by two strings from a sup-
porting rail. The adjusting screws on the clamps are
used for setting the horizontal alignment of the
wheel. Two axle hubs fitted at the end of the axle
prevent the wheel from breaking out during its up-
and-down motion.

Maxwell's wheel U8408305
130 mm
470 g
10 kg cm²
370 mm x 12 mm dia.
For setting up Maxwell's wheel, the following appa-
ratus is additionally required:
1 Retort stand, H-base
2 Stainless steel rods, 1000 mm
2 Universal clamps
•
Set up the stand rods on the base as shown in
Fig. 1.
•
Attach the clamps supporting Maxwell's wheel
to the horizontal rod.
•
Use the adjustment screws to align the wheel
so that the axle is in a horizontal position.
•
Gradually move the wheel upwards winding
the strings around the axle. Make sure that the
axle remains in a horizontal position. If neces-
sary, readjust the strings.
•
With the wheel at its maximum height, start
the movement of the wheel.
