The Foucault Pendulum is a piece of apparatus for qualitative and quantitative demonstration of the Earth's rotation. This is done though observation of the pendulum's plane of oscillation.
The pendulum comes in a stylish box which is well -lit to catch the eye.
The pendulum passes through a Charron Ring, in order to prevent its oscillation taking an elliptical orbit. This helps make the demonstration of this phenomenon easier to see visually and more consistent.
To provide quick results, the pendulum string's shadow is projected onto a protractor scale. Because of this, it quickly becomes easy to see the changes in the pendulum's plane of oscillation.
An electromagnetic boost is applied to the pendulum to prevent the gradual dampening of the oscillation. This is ideal for longer periods of observation, where the dampening of the oscillation can make it harder to see the oscillation plane over time.
A Range of Experiment Topics
The pendulum enables a range of experiment topics to be covered:
- Pendulum oscillations
- Rotation of the Earth
- Coriolis force
