The Voyager Magnetometer Experiment (MAG) is one of ten experiments carried onboard the two Voyager spacecraft. Voyager MAG consists of two low field magnetometers and two high field magnetometers that together provide measurement of fields from 0.02 nT to 2,000,000 nT (20 G). The Voyager magnetometers were built at NASA Goddard Space Flight Center where the project resides. The magnetometers provide direct field measurement of both the planetary and the interplanetary plasma media. Having completed their exploration of our Solar System's outer planets and interplanetary medium, the Voyager magnetometers are now a key component of the Voyager Interstellar Mission, collecting measurements of magnetic fields far from the Sun. Research efforts continue as the two Voyagers fly on towards the heliopause and the interstellar media that lays beyond.
