MANE6960 Advanced Topics in Finite Elements Homework 3 Steady State Electromagnetics Laplace’s and Poisson’s equations govern the distribution of electric and magnetic potential in steady electromagnetic systems. In electrostatics, Laplace’s equation applies for the electric potential when there are no sources or sinks of charge within the region being analyzed, Poisson’s equation otherwise. In magnetostatic systems, the magnetic potential is governed by Laplace’s equation when there is no current flow , Poisson’s otherwise. In this project you will create a finite element model to estimate the potential distribution in a selected situation. You must choose one of the following settings and use the data provided plus any other information that you may need to create a finite element model to predict the potential in the given configuration. Perform appropriate verification and validation experiments to substantiate the reliability of your model. 1.- Electric potential distribution near a selected galvanic junction in seawater. 2.- Electric potential, electric field, magnetic potential and magnetic field near a radius discontinuity in the inner conductor in a round coaxial cable. 3.- Magnetic potential in an electrical machine rotor slot.
