Geomagnetism

Science > Physics > Magnetism > Magnetic Field and Geomagnetism The branch of physics which deals with the study of earth’s magnetic field is called terrestrial magnetism or geomagnetism. The magnetism on the surface of the earth can be approximately represented by assuming a huge imaginary bar magnet in the interior of the earth. The […]
