| Abstract: | The analytical solutions of the vector potential and magnetic induction intensity of the infinitely long current carrying thin plate are derived,the equations are transform into the dimensionless form,the vector potential and magnetic induction intensity are also calculated;the vector potential and magnetic induction intensity curves on the midperpendicular plane and on the plane of the plate are drawn,and compared it with that of the straight line current;and the two components of the vector potential and magnetic induction intensity as well as the combined magnetic field and the directional surface are also depicted,the two dimensional magnetic induction line are drawn,which reveals the distribution rule of magnetic induction intensity. |
