A tool for magnetically locating and recovering an electrical wire suspended within a hollow wall. The tool includes a buoyant magnet suspended in a clear liquid within a transparent container. A rod-like plastic handle is used to manipulate the container along a wall behind which a magnetizable iron member is hanging from the lower end of the electrical wire to be located. A plurality of cylindrical magnets joined end-to-end by flexible linkages are affixed to the opposite end of the plastic handle.
