Пристрій для спостереження руху елементарних частинок на повітряній подушці
Experiment topics:
• Thermal motion of atoms and molecules in various states of aggregation
• Electrical conduction processes
• Models of atomic physics
• Mechanical motion

An ideal device for demonstrating a series of experimental models intended to study the motion of atomic particles:
a) Objects hovering on the air cushion experience near zero friction and are used to simulate particle motion. The set contains five different transparent, coloured plastic or aluminium elements with round ceramic magnets fitted to them to ensure elastic collisions.
b) Magnetic barriers can be used to modify the plastic-bordered experimentation surface. This allows elastic collisions between the hovering bodies and the borders.
c) A lattice model with a fixture is available for emulating crystal lattices in experiments on electrical conductivity in semiconductors, for instance. Comprises a height adjustable plexiglass plate from which 25 ceramic magnets are freely suspended.
d) Two rod-shaped metal electrodes can be positioned in parallel with the experimentation surface in order to generate an electrical field. The effect of electrical fields on charged particles can also be simulated by inclining the experimentation surface.
The equipment system is characterized by a clear and simple design, minimum preparatory adjustment requirements, clear visibility of all experiments through overhead projection, simple operation and high reliability.
The device consists of a robust frame with a pressure chamber whose cover plate is furnished with 1 089 fine perforations and serves as an experimentation surface. Air is supplied to the pressure chamber by a blower via a hose, causing the coloured bodies to hover. An additional air stream from an impulse valve makes it possible to alter the motion of the hovering bodies. The air cushion plate is equipped with two adjustment screws for horizontal alignment.
