椭圆形

Circular electric current is a classical physical model. The researches on the magnetic field distribution characteristics of the circular current are helpful for the further study on magnetic characteristics of magnetic dielectric. The ellipse electric current is a typical physical model of ring-like electric current. The researches on the magnetic field distribution of it make us obtain more understandings of magnetic problem of ring-like electric current.
