Other AbstractThe Sun's magnetic fields, differential rotation and plasma convection give rise to complexity in the magnetic structure and activity over a large range in both spatial and temporal scales.The most notable among these is the solar activity cycle of 11 years, or magnetic cycle of 22 years.On small time scales of a few seconds to several hours,spectacular explosive events occur in the solar atmosphere, such as solar flares, prominence eruptions and coronal mass ejections.These forms of activity are all closely related to solar magnetic fields (SMF).This paper focuses on the introduction of SMFs'origin,the related observational technique, SMFs' distribution and evolution, and several associated typical characteristics, such as the complexities, active longitudes and active holes, the periodicities,and so on.The detailed content is organized as follows.In section 1, four typical forms of solar magnetic activity (sunspot, flare,filament,and coronal mass ejection) and their corresponding theoretical models are described briefly.Section 2 is devoted to solar dynamos responsible for explaining where SMF comes from and the course of instrument development built for observing it at higher and higher temporal and spatial resolutions.Section 3 summarizes the laws of SMFs'distribution and evolution on different spatial scales,including magnetic fields associated to active regions, quiet sun, aad network,intra-network magnetic fields, obtained by using magnetograms and soles activity catalogues. Finally, some associated unresolved problems and highlights are discussed in the last section.
