This paper deals with a coupling scheme for open boundary problem. It couples an analytical solution of Fourier series expansion with the standard finite element method. The analytical solution is derived for the magnetic field in the outside of the boundary, and the finite element method is for the magnetic field in the inside with source current and magnetic materials. The main advantage of the...
In this paper, a new, general form of the equivalent magnetizing current method is proposed for calculating the total force of magnetized bodies in contact, including ferromagnetic and permanent magnet. This method is formulated in way similar to the generalized equivalent magnetic charge method. It provides consistent numerical results of force calculation, whether or not one magnetized body is in...
Here, to calculate the electromagnetic body force density and total force the expression for Kelvin force density was expanded by incorporating the virtual air gap scheme. Conventionally, this Kelvin force density can be utilized by using external applied field and total field acting on a dipole. Since there is no well-accepted manipulating technique, it has been difficult to directly compute the...
