Three dimensional (3D) null point topology plays an important role in studying the dynamics of transients in the solar corona. Although ubiquitous, the generation of these nulls is still an unsolved question. To address this problem, consider the magnetic strength of the (n-1) magnetic dipoles at a point P is -B. Suppose we put nth magnetic bipole of strength +B at the same location. Now we are able to construct a 3D null by this method. However, the stability of this type of special structure is uncertain. To understand this problem, we have tried different initial value problems to check the self-organized nature of the 3D nulls. Important is our simulation results which validate the above argument. |
