Technique of Magnetic Measurements,struments. These instruments, essentially magnetometers, are distinguished not only by the component of the field they measure, but also by the principle of their working. The principles employed in magnetometers range from the elementary laws of forces acting on a magnetic needle, to the technique

This is a multidisciplinary science and magnetic observatories (MOs) provide data to those institutes, whose interests range from geology, subsurface structural mapping, geophysics (including seismology and earthquake prediction), meteorology, solar-terrestrial physics, and astronomy

The other major contributions relate to understanding of the generation of EMF, palaeointensity, relative movements of continental blocks, co

The redistribution of the charged particles in turn can modify the existing electric and magnetic fields in the atmosphere. Hence, an invest

For studies related to different fields, suitably located MOs are operated throughout the country (Fig. 1.14) and worldwide (Fig. 5.1) to record strength, intensity, and direction of the geomagnetic
