FEM Solutions

FEM mesh created by an analyst prior to finding a solution  to a magnetic problem using FEM software. Colours indicate that the analyst has set material properties for  each zone, in this case a conducting wire coil in  orange; a ferromagnetic component (perhaps iron) in light blue; and air in grey. Although the geometry  may seem simple, it would be very challenging to calculate the magnetic field for this setup without FEM software, using equations alone. FEM solution to the problem at left, involving a cylindrically shaped magnetic shield. The ferromagnetic cylindrical  part is shielding the area inside the cylinder by diverting the magnetic field created by the coil (rectangular area  on the right). The color represents the amplitude of the magnetic flux density, as indicated by the scale in the  inset legend, red being high amplitude. The area inside the cylinder is low amplitude (dark blue, with widely spaced lines of magnetic flux), which suggests that the  shield is performing as it was designed to.
