India’s first indigenous Overhauser Magnetometer

• OVH Magnetometers are known for their higher accuracy, higher sensitivity, and efficient power consumption.
• The Indian Institute of Geomagnetism (IIG), an autonomous research institution under DST, has developed the Magnetometers.
• A team from IIG’s instrumentation division used various spectroscopic tools and theoretical simulations to understand the working.
• They 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.

Benefits of OVH magnetometers

• OVH magnetometers reduce the cost of sampling and sensing experiments essential for geomagnetic sampling.
• It can reduce India’s dependence on commercial OVH magnetometers for performing geomagnetic field measurements.
