This paper investigates the structure of a spin electromagnetic (EM) field and its various physical properties.A spin EM field is an intrinsic mode of free space,which satisfies the spin equations derived from Maxwell equations.A spin mode has two basic properties:the spin along its axis and the localization of electromagnetic field.The source and EM structure of this electric and magnetic mode are described in detail in this paper.The distributed charge and current of a spin mode can be integrated to obtain the electric and magnetic moment,and they can be treated as the electromagnetic dipole.A spin mode possesses both wave and particle properties:a wave number,angular frequency and characteristic speed are its wave parameters;an intrinsic radius,energy and angular momentum are its dynamic parameters.The former is analogous to an EM resonant mode;the latter is similar to the behavior of a particle with intrinsic spin.There are two kinds of electric modes present,one can be expressed through a pair of charges,and the other can be expressed by a magnetic current.They both have the same electric moment,but have different divergence properties. 展开更多
