  In electromagnetic analysis, the finite element and boundary element methods
jointly known as 'FEM-BEM coupling' is applied for numerically solving
levitation problem based on eddy current. The main focus behind this coupled
analysis method is to determine the dynamic characteristic of the levitating
body in the presence of a magnetic field. An innovative 3D structure is
developed that couples Lagrangian description and BEM-FEM coupling method for
this purpose. The coupling methodology is based on the boundary conditions on
the common boundaries between FEM and BEM sub-domains. Subsequent coding has
been developed to simulate the problem in the MATLAB environment. An example
similar to TEAM (Testing Electromagnetic Analysis Methods) workshop problem 28
has been used to study the efficiency of code for computationally inexpensive
analysis.
