Free Physics Experiment - If you use this please let us have your feedback.


This page gives you free access to some of our Immersive 3d Physics experiments from the Virtual Physics Laboratory.  Please make sure you read the instructions before trying the experiments.  It is very important that you know how to navigate around the laboratory and how to interact with the various controls within the experiment.  These are briefly:


 Move using cursor keys and PageUp/Down to change height.

 Change view using mouse with right button held down.

 Click on switches to change state.

 Use mouse wheel on rotating knobs.

 Use +/- to zoom in and out.

 Use switches on projector to change slide being projected.

Click right and choose full-screen for a better display (leave full-screen by pressing Escape).


Note that the first time you run one of these experiments you may need to install the Unity Plug-in which will happen automatically, but you may need Administrator privileges.  If you have problems consult your network manager or contact us and we will sent you a runnable version on a CD which does not need installing.



This is a virtual experiment to investigate the magnetic field produced by a coil.  The number of turns on the coil can be selected.  The maximum amps and voltage can be selected on the power supply and the actual amps read from a multimeter.


A magnetometer allows the reading of the deflection caused by the magnetic field.


This experiment can also determine the horizontal component of the local magnetic field due to the Earth.

The Virtual Physics Lab comprises the following experiments: Airtrack for average speed and acceleration; Airtrack for Newton’s second law; Boyle’s Law; Capacitor charge and discharge; Charles’ Law; Diffraction of Monochromatic Light; Inverse Square Law for Gamma Radiation; Gravity on Earth, Moon and Mars; Hooke’s Law and Young’s Modulus; Internal Resistance; I/V Characteristics for Diode and Filament bulb;  Magnetic Field Line Demonstrator; Magnetic Field of a Coil and the Earth; Magnetic Flux Linkage; Mass-spring System; Moments; Momentum using Ballistic Balance; Planck’s constant using coloured LEDs;Specific Heat of Brass; Mechanical Equivalent of Heat; Moments; Millikan’s Oil Drop; Resistivity of Constantin; Rutherford’s gold foil;


Please email us using the ‘Contact us’ menu to let us know what you think or what experiments you would like to see in the lab.  It is very important that we get feedback to enable us to provide you with what you need.
