Projects and exercises for electrostatics

This post lists a number of calculations where SATE can be used in a class on introductory electromagnetism. The emphasis is on problems where a numerical calculation can be compared to analytic results. These examples use EStat. A second post (http://www.fieldp/myblog/?p=34) lists suggested magnetic-field calculations. This page may change from time to time as I come [...]

Resources for electromagnetic education

We will release Version 3.0 of our free educational package for electric and magnetic fields on Monday, May 12 (2008). The SATE (Static-field Analysis Toolkit – Educational) package includes the latest versions of our 2D programs Mesh. EStat and PerMag along with complete instruction manuals. We have made the following improvements:

The number of nodes and materials [...]

How to calculate inductance (3)

In the final installment, we will look at a 3D example of the calculation of mutual inductance. Discussions in this blog have also been added to the Magnum manual (Chapter 13) You can download the latest version at

The example illustrates the energy method described in the previous article (http://www.fieldp.com/myblog/?p=31) applied to a two-circuit system, a high-voltage [...]

How to calculate inductance (2)

This article continues the discussion of how to use 2D and 3D numerical codes to find inductance. The first article [How to calculate inductance(1)] covered the use of the energy method for simple systems with a single circuit. An example showed the application of static-field codes to estimate inductances of current-carrying rods in both the low [...]
