Rapid changes in instrumentation have led to the monitoring of geomagnetic fields and fluctuations on land, under the oceans and in space.

Adoption of Sophisticated analysis techniques and fast computers over a period of time have opened up new vistas for practical utilization of geomagnetic measurements and which resulted in many milestones for Indian Institute of Geomagnetism.

Recognising the importance of fostering scientific pursuits in geomagnetism, in 1971, the Colaba-Alibag Observatories were converted into an autonomous research organisation called the "Indian Institute of Geomagnetism" by the the Government of India.

Objectives and functions of the Institute are:

• To establish, maintain and manage laboratories, workshops and/or other units to assist scientific research in Geomagnetism.
• To record, collect, scrutinise, process, publish and supply geomagnetic data.
• To undertake the design, development, construction calibration and standardisation of magnetic instruments.
• To organise training facilities and to train the staff of the Institute and other interested organisations in geomagnetic work and arrange lectures, seminars and symposia in pursuance of the academic work of the Institute and for diffusion of scientific knowledge.
• To invite Scientists from India and abroad who are actively engaged in research in geomagnetism, to deliver lectures and participate in the research activities of the Institute.
• To institute and award fellowships, scholarships, prizes and medals.
• To co-operate and collaborate with other National and/or foreign institutions and international organisations in the field of Geomagnetism.
• To publish scientific papers, bulletins and journals.
• To disseminate information on matters concerning geomagnetism.
