Abstract

The integral formulas of magnetic field of ring current are derived in the dimensionless forms. The

magnetic field is calculated by the numerical integration，and its spatial distribution is visualized by means of MATLAB.

The analytic solutions of the magnetic field of ring current are also derived，and its validity is verified according to their graph.

Key words： ring current; magnetic field; numerical integration; dimensionless diagram
