| In this paper, the interaction energy and the magnetic field distribution of acircle current are firstly reviewed and then lucubrated. Interaction energy and forcebetween two coaxial rings are obtained. The spatial distribution diagram for force isplotted. Variation of the force with distance and radius of the rings are discussed,too. The magnetic field distribution of a circle current is obtained in a series form incylindrical coordinate system. The third part is about a model for the oscillation ofnon-harmonic oscillators. At last, physical model and computer simulation isintroduced. The calculation of interaction energy and electrical model are relatedwith elliptic integral. |
