From the Back Cover
The physicist Michael Faraday said that the study of magnetic lines of force was greatly influential in leading him to formulate many of those concepts that are now so fundamental to our modern world, proving to him their "great utility as well as fertility." Michael Faraday could only visualise these lines in his mind's eye and, even with modern computers to help us, it has been very expensive and time consuming to plot lines of force. The book also explains how the new method and numerical equation solving algorithms work.
* An overview of the physics of magnetic fields
* A complete description of the theory behind the new technique
* An overview of the theory of Gaussian elimination and Conjugate Gradient equation solvers (including a software application to visualise the algorithms in action)
About the Author
John S. Beeteson retired as a senior research scientist at IBM Greenock in 1998 after 20 years with IBM. He holds 40 US patents and many others worldwide, and was the inventor and co-inventor of two new magnetically based display technologies. Prior to joining the digital computer industry, Mr. Beeteson worked on radar systems and analogue computing.

The use of numerical analysis tools is widely regarded as essential for more than the simplest of geometries. Frequently these tools require a substantial knowledge in order to be able to apply them to the problem at hand. With the use of the author's visualisation of numerical solvers in action the user is able to understand how the computation process develops in solving in 2D a mathematical representation of the field problem. This understanding is essential if the reader wishes to progress to the more challenging 3D simulation environment, especially for those creating rather than just applying the simulation software.
Overall I found the book useful as a means of introducing the subject and would recommend it to students in their last year of school or as an introductory text in undergraduate studies. In addition to students of Physics and Electrical Engineering, the underlying concepts covered are similar to those for mechanical analysis (stress, strain, distortion) and computational fluid dynamics, including heat flow problems. Thus students in the other Engineering disciplines will find something useful in the book and especially the accompanying software.
Here, the reader can simulate almost any combination of magnets, conductors and external fields and visualize the result in a number of different ways. So this book and its accompanying software will find use in grade school, universities and industry. The visual impact of the approach used by John Beeteson should prove inspirational to younger students. I would recommend that any teacher involved in this subject should buy this book and try it out.
I have used the software on a W98 notebook computer and on a powerful dual processor NT machine. It works just fine in both cases.
