초록

Circular coils are widely used in electromagnetic applications, and the force in a sets of coils consisting of more than two can be divided into three components. Among them, one component called radial force is acting on the radial axis, and it is exposed as stree or impact. Calculation of the radial force was used to be performed by introducing Ampear's law of force which is $F=J{\times}B$. However, many cases in analyzing a system, calculation method from the mutual inductance between the coils is oftenly employed to get the axial force and resulting dynamics. In this case, if the calculation of radial force from the mutual inductance is possible, flow of the calculation for the system analysis would be much more simpler.
