Detailed explanation-1: -Alibag Magnetic Observatory is India’s first geomagnetic observatory. This observatory was established in 1904. It is situated in Alibag, Maharashtra.
Detailed explanation-2: -Indian scientists have developed an Overhauser Magnetometer, one of the most accurate magnetometers extensively used by all magnetic observatories around the world, making way for reducing the cost of sampling and sensing experiments essential for geomagnetic sampling.
Detailed explanation-3: -The Indian Institute of Geomagnetism (IIG), an autonomous research institution under DST, has developed the Magnetometers.
Detailed explanation-4: -India’s dependence on imported overhauser magnetometer (OVH) used for geomagnetic field measurements could soon be reduced as scientists will be able to use an indigenously developed OVH.
Detailed explanation-5: -The most sensitive, commercially available magnetometer is the Potassium magnetometer/gradiometer system.
