Fluxgate Magnetometer

Target entity: Fluxgate Magnetometer
Context triple: [Deep Space Climate Observatory, instrument, Fluxgate Magnetometer]

• A. Magnetes
  Magnetes were an ancient Greek tribe from the region of Magnesia in Thessaly, known from myth and history as participants in wider Hellenic religious and political affairs.
• B. Wood–Anderson torsion seismometer
  The Wood–Anderson torsion seismometer is an early 20th-century mechanical seismograph designed to measure local earthquake ground motion with high sensitivity, forming the instrumental basis for the original Richter magnitude scale.
• C. Alderson disk
  An Alderson disk is a hypothetical megastructure consisting of a gigantic, flat disk-shaped habitat encircling a star, proposed as an extreme example of astroengineering and space-based living space.
• D. Fine Guidance Sensor
  The Fine Guidance Sensor is a high-precision pointing and stabilization instrument on the James Webb Space Telescope that locks onto guide stars to keep the observatory accurately aimed during observations.
• E. South Pole Telescope
  The South Pole Telescope is a large millimeter-wave radio telescope located at the Amundsen–Scott South Pole Station, designed primarily to study the cosmic microwave background and the large-scale structure of the universe.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
