Scientists at the Indian Institute of Geomagnetism (IIG) an autonomous institution of the Department of Science and Technology (DST) developed a generalized one-dimensional fluid simulation code capable of studying a wide spectrum of coherent electric field structures in near-earth plasma environment or earth's magnetosphere.
New simulation code: ♦ The new simulation code can be useful in planning future space missions. ♦ It can also lead to precisely controlled fusion laboratory experiments for ever-expanding energy needs of humanity. ♦ The study was focused on the coherent electric field structures that are observed in the high-resolution electric field waveform data and can be seen as isolated pulses of various forms. ♦ The complex and nonlinear wave phenomena in the magnetosphere studied by the IIG team will help advance the knowledge of plasma waves, instabilities, and coherent effects.
How is Magnetosphere of the earth created? Sun is the major source of plasma deposition in space around the Earth. Sun forces some of its plasma towards the earth in the form of the solar wind. The speed of this wind varies between 300 to 1500 km/s, which carries with it a solar magnetic field, called Interplanetary Magnetic Field (IMF). The interaction of the IMF with the earth's magnetic field creates the magnetosphere of the earth.
