This paper presents a method to obtain the magnetic field resulting from currents in coils and permanent magnets in structures with axial symmetry and open boundaries. The finite element method (FEM) is used inside a sphere containing the structures and a Legendre polynomial expansion is used to represent the field in the outside region. The polynomial… CONTINUE READING
