The analytical solutions of the magnetic field of Helmholtz rings in the rectangular coordinate are derived,and they are dimensionless. The components of magnetic field are obtained by means of the complete elliptic integral of first and second kinds. The distribution of magnetic field is plotted by means of MATLAB. It is found that the range of uniform field is octopus shape. Furthermore,the change of the range of uniform field with the distance between two current coaxal rings is discussed
