The importance and actuality of investigation Space Magnetic Traps in the Universe and in Magnetosphere are based on following four factors: 1. Space Magnetic Traps in the Universe for Cosmic Ray particles (Astroparticles, Run Away Particles) on different studies of the Universe's evolution and in different objects (galaxies of different types, quasars, nucleus of galaxies, Sun and stars, Heliosphere and Stellar Spheres, solar and stellar winds, magnetospheres of planets, and so on) are very interested and important in the frame of fundamental science (Astrophysics, Plasma Physics and Magneto-Hydrodynamics, Nuclear and Elementary Particle Physics, Geophysics). This problem is interested also for applications (e.g., problem of controlled thermo-nuclear reactions in magneto-plasmas traps as main source for energy in near future for the Earth's Civilization). 2. The Magnetosphere is the nearest giant natural laboratory where with satellites and ground measurements is possible to investigate different plasmas and energetic processes in space caused by interaction of high kinetic energy solar wind plasmas with frozen in Interplanetary Magnetic Fieldsï­IMF and its perturbations (Interplanetary Coronal Mass Ejectionsï­ICMEs, Interplanetary Shock Wavesï­ISWs, Interplanetary Interaction Regionsï­IIRs, and so on) with the rotated main geomagnetic field. This interaction leads to a dynamic transformation of magnetic fields in the Magnetosphere, formation Space Magnetic Traps (Radiation Belts), generation and trapping of high energy particles (which can be called Magnetospheric Cosmic Raysï­MCR), and generation of different types of instabilities and electromagnetic radiations. These processes are similar to processes in magnetospheres of other planets and their moons, in the atmosphere of the Sun and other stars, in interplanetary and in interstellar space, and in many different astrophysical objects in the Universe. This research presents an important basis for fundamental space in frame of Astrophysics, Plasma Physics and Magneto-Hydrodynamics, Nuclear and Elementary Particle Physics, Geophysics. 3. In modern time, technology, economics, navigation, TV, internet, radio-connections, military aspects, and the life of people on our planet are strongly connected by the work of many satellites moving inside the Magnetosphere. Different processes and MCR in the magnetosphere influence how the satellites work and often lead to satellite malfunctions, sometimes completely destroying their electronics and satellites become 'dead'. The described research can be considered as a basis for developing methods of forecasting dangerous situations for satellites on different orbits and to decrease the risk of satellite malfunctions and of losing them. It means that this research has important practical applications. 4. The interaction of ICME, ISW, and IIR with the Magnetosphere leads to the generation of big magnetic storms accompanied by Cosmic Ray Forbushï­decrease and precursory effects in Galactic Cosmic Ray (GCR) intensity. These magnetic storms are dangerous, not only for satellites, but also for Earth's surface regarding technology, radio-connections, car accidents, and human health (e.g., increasing frequency of infarct myocardial and brain strokes). Investigation of causes of magnetic storms can help to develop methods of their forecasting and decrease the level of magnetic storm hazards. Therefore, the other practical application of this research is connected with the problem of space weather and space climate influence on the technology, radio-connections, navigation, transportation, and human health on the Earth in dependence of altitude and geomagnetic latitude.

The importance and actuality of the Geomagnetosphere's research are based on following three factors: 1. The Geomagnetosphere is the nearest giant natural Laboratory, where is possible by a lot of satellites and ground measurements investigate in details many different plasmas and energetic processes in space, caused finally by interaction of high kinetic energy solar wind plasmas and its perturbations (Interplanetary Coronal Mass Ejections - ICMEs, Interplanetary Shock Waves - ISWs, Interplanetary Interaction Regions - IIR) with frozen in Interplanetary Magnetic Fields - IMF with the rotated main geomagnetic field. This interaction leads to dynamic transformation magnetic fields in Geomagnetosphere, generation and trapping high energy particles (which can be called as Magnetospheric Cosmic Rays - MCR), generation of many types instabilities and electromagnetic radiations. These processes are in principle similar to processes in magnetospheres of other planets and their moons, in the atmosphere of the Sun and other stars, in interplanetary and in interstellar space, in many different astrophysical objects, i.e. this research is important basis for fundamental Space and Astrophysical science. 2. In the modern time the Technology, Economics, Navigation, TV, Internet, Radio-Connections, Military aspects, and the life of people on our planet are strong connected with the work of many satellites, moving inside the Geomagnetosphere. Different processes and MCR in the Geomagnetosphere influenced on the satellites work and often lead to satellite malfunctions up to full destroying work of their electronics - satellites became 'dead'. The described research can be considered as basis for developing methods of forecasting dangerous situation for satellites on different orbits and to decrease the risk of satellite malfunctions and loosing, i.e. this research has important practical application. 3. The interaction of ICME, ISW, and IIR with Geomagnetosphere leads to generation big magnetic storms accompanied with Forbushdecreases and precursory effects in Galactic Cosmic Ray (GCR) intensity. These magnetic storms are dangerous not only for satellites, but also on the Earth's surface for technology, radio-connections, car accidents, people health (e.g., increasing frequency of infarct myocardial and brain strokes). Investigations of causes of magnetic storms can help to develop methods of their forecasting and decreasing the level of magnetic storms hazards. Therefore, the other practical application of this research is connected with the problem of space weather and space climate influence on the technology, radio-connections, navigation, transportation, and people health on the Earth in dependence of altitude and geomagnetic latitude. The present book "Energetic Particles in Geomagnetosphere/Ionosphere" contains the following Chapters: Chapter 1. Experimental Evidences on Energetic Particles in the Earth's Environment Chapter 2.
