Magnetic field models of the Earth''''s magnetosphere
地球磁层的磁场模型

A half of a century has passed since the Earth's magnetosphere was discovered by satellite Explores in 1958.Studies on space physics cover a wide range of topics: electromagnetic fields,electric currents,particles,plasma waves et cetera.Various models have appeared for describing our electromagnetic environment.This paper reviews the progresses of magnetosphere modeling,their basic principle and methodology.More than one dozen of magnetospheric models are discussed and compared on their characteristics,limitations and validity.
