  The phenomenon of linear motion of conductor in a magnetic field is commonly
found in electric machineries such as, electromagnetic brakes, linear induction
motor, electromagnetic flowmeter etc. The design and analysis of the same
requires an accurate evaluation of induced currents and the associated reaction
magnetic fields. The finite element method is a generally employed numerical
technique for this purpose. However, it needs stabilization techniques to
provide an accurate solution. In this work, such a stabilization technique is
developed for the edge elements. The stability and hence the accuracy is
brought in by a suitable representation of the source term. The stability and
accuracy of the proposed scheme is first shown analytically and then
demonstrated with the help of 2D and 3D simulations. The proposed scheme is
parameter-free and it would require a graded regular mesh along the direction
of motion.
