Line 25:
In the user manual it says The 3B Foucault pendulum is a compact
apparatus which maintains the amplitude of the pendulum by '''constant excitation'''. An '''electromagnet''' with a radially symmetric magnetic field is mounted exactly in the middle of the pendulum's path. The magnet only has an effect when the pendulum is moving towards the center. The electromagnet is controlled by a photovoltaic cell which registers the shadow of the pendulum motion by the light provided by a built-in fluorescent lamp. '''The pendulum is excited in a way such that its amplitude remains constant.''' <ref name=3bscientific></ref>
=== A Foucault's Pendulum at the south pole proves globe erf? ===
Just in time for the holidays, Jeran at Jeranism found an article about a Foucault's Pendulum at the south "pole". After some heavy modification, the "scientists" were sure they have solid globe proof. There's no way they would lie; You might, but NOT them! <ref name=christmaspole></ref>
