Dip circle can be used to determine the angle of dip at a place. Dip circle consists of a magnetic needle free to rotate in a vertical plane. The end points of the needle move over a vertical circular scale. This arrangement can rotate about vertical axis. The angle rotated about vertical axis can be read from a horizontal scale.

A dip circle can be used to determine the angle of dip at a place. A dip circle consists of a magnetic needle free to rotate in a vertical plane. The endpoints of the needle move over a vertical circular scale. This arrangement can rotate about a vertical axis. The angle rotated about the vertical axis can be read from a horizontal scale.
