The three-axis flux gate magnetometer electronics were designed and built by Marshall Laboratories of Torrance, Calif., under the supervision of the Jet Propulsion Laboratory, represented by Benjamin V. Connor, the magnetometer project engineer. The experiment is supported by the National Aeronautics and Space Administration under contracts NASw-6 (E.J.S.), NsG 151-61 (L.D.), and NsG 249-62 (P .J.C.); The sensor was designed and fabricated by Institut Dr. Förster, Reutlingen, Germany.

Mariner II magnetometer data gave no indication of a Venusian magnetic field. This implies, by comparison with spacecraft measurements near Earth and with theoretical models, that the magnetic dipole moment of Venus is at most 1/10 to 1/20 that of the earth.
