Abstract :
The paper discusses the magnetic field of calculable resistor of toroid type which influences the transform of AC/DC quantum Hall resistances standard. Theoretical models are built based on the complex logarithm transform function. Thus, the distribution of magnetic field can be obtained. It also displays the distribution of main magnetic flux and the leakage flux. Furthermore, the equations of boundary magnetic field line and the position of the boundary on the axis can be calculated theoretically on the model.
