India’s First Indigenous Overhauser (OVH) Magnetometer

India’s First Indigenous Overhauser (OVH) Magnetometer:

Indian scientists have recently developed an Overhauser Magnetometer.

  • The Indian Institute of Geomagnetism (IIG), an autonomous research institution under Department of Science & Technology, Government of India, has developed the magnetometer as part of its technology development program.
  • It will pave way for reducing the cost of sampling and sensing experiments essential for geomagnetic sampling.
  • The performance of this indigenously made magnetometer is at par with a commercial OVH sensor that is currently installed at the magnetic observatories of IIG.
  • Overhauser Magnetometer is one of the most accurate magnetometers extensively used by all magnetic observatories around the world.
  • They are known for their higher accuracy, higher sensitivity, and efficient power consumption and hence find applications in all magnetic observatories worldwide as well as in international space programs.
  • It has so far been imported for such purposes in India.
