Abstract
An apparatus for detecting movement downhole includes a first downhole component () having a sensor () coupled thereto and a second downhole component () positioned relative to the first downhole component (). The sensor () generates a primary magnetic field that is imposed on the second downhole component () thereby generating an induced magnetic field that interacts with the primary magnetic field. Movement of the first downhole component () relative to the second downhole component () is detected by the sensor () by sensing a change in the induced magnetic field.
