Abstract

Abstract:

The mutual inductance coefficient between two coaxial circular currents is visualized by means of dimensionless method proposed here. The relationships of the mutual inductance coefficient with the radius and distance between the two circular currents are displayed according to these graphs. Moreover，the method of calculating the axial and radial forces between the two coaxial circular currents is discussed. The two forces are visualized by means of dimensionless method. The relationships of force with the radius and distance between two circular currents are shown.

Key words: coaxial circular current, mutual inductance coefficient, axial and radial forces, dimensionless drawing, elliptic integral
