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.
