Magnetic Levitation Force and Torque Analysis of a Diamagnetic Material Using Nodal Force Method

Abstract

When the force to be calculated is very small, it is not easy to determine this force with high accuracy using the nodal force method because of the discretization errors that may occur in the finite element analysis (FEA). In this study, we investigate a technique to calculate the force with high accuracy based on the magnetic levitation force and the torque analysis of a diamagnetic material. The levitation force can be calculated with high accuracy using the extreme fine mesh in the domain integration of the nodal force. Extremely small torque values can be calculated with high accuracy by symmetrizing the mesh in the domain of integration of the nodal force.
