Foucault pendulum was designed to demonstrate the rotation of the earth. The observatory pendulum is a 240 pound brass sphere suspended from a 40 foot steel wire. Once started, it continues to swing in the same direction. A ring magnet above the ceiling keeps the pendulum in motion without influencing the direction of its swing. Every ten minutes or so the pendulum knocks over a peg, but it is not the pendulum that has moved over to hit the peg. The earth has moved the peg into the path of the swinging pendulum. The pendulum is essentially disconnected from the turning of the earth and once started in motion, it continues to swing in the same direction regardless of what the earth does. The earth rotates beneath it, making it look as if the pendulum is changing its direction of swing.
