A pendulum of crystal, metal or other materials suspended on a chain is sometimes used in divination and dowsing.
In one approach, the user first determines which direction (left-right, up-down, clockwise, counter clockwise) will indicate a yes, no or maybe, before proceeding to ask the pendulum specific questions; or else another person may pose questions to the person holding the pendulum.
The pendulum may also be used over a pad or cloth with yes and no written on it and perhaps other words written in a circle. The person holding the pendulum aims to hold it as steadily as possible over the center and its movements are held to indicate answers to the questions.
In the practice of radiesthesia, a pendulum is used for medical diagnosis.
