ABSTRACT:
An apparatus for demonstrating, investigating and observing Brownian motion and temperature of a medium, such as gas or liquid, uses a small particle which is diamagnetically suspended in the medium. The tiny magnetized particle having a known mass is levitated using a diamagnetic technique, and the displacement of the particle over time is observable, which can be used to determine a temperature of the medium. Optionally, a second particle is suspended in a vacuum but mechanically connected to the same apparatus as the first enclosure with the first particle, thereby allowing observation and measurement of non-Brownian movement of the structure, and allowing more precise observation of Brownian movement effects on the first suspended particle.
