Earth radiation belt and inner magnetosphere show pronounced difference in their charatacteristic as interplanetary magnetic field and solar wind properties change over the 11 year solar cycle. Solar transients almost invariably enhancing highly relativistic electrons. Van Allen radiation Belt has found to contain nearly impenetrable barrier that prevents the fastest, most energetic electrons fro reaching earth atmosphere. the van allen probes will help to understand the Sun's influence on the earth atmosphere and near earth. thus importance of to studying of van allen radiation to understand space weather event. Solar energy and cosmic radiation have electrical influences over a multitude of human activities including human health. the cyclical variations in the sunspot number of the Solar Cycle in order to create a mass index of human excitability throughout history. The Sun is an enormous generator of electric energy and emits it in the form of radiation and induction. The Sun is surrounded by an electromagnetic field, the limits of which reach beyond the farthermost planet.
