3D Physics - Electricity/Magnetism

It would be useful to simulate the forces generated by Electric / Magnetic fields, to allow virtual electric motors for example to be built.

However I'm not sure that users would want to build every motor from first principles. I think perhaps an electric motor should be a standard building brick without needing to simulate its internal workings.

Example of such a Program (written in C++ not Java) :

RADIA

A software for 3D magnetostatics. It is optimized for all sort of accelerator magnets such as undulators, wigglers, dipole and quadrupole magnets. It uses a a finite volume integral approach. It handles current coils, non linear iron type material and anisotropic permanent magnet type materials of arbitrary shape. Radia computes very accurately the integrated field components (dipole, quadrupole,..)

Book Shop - Further reading.

Where I can, I have put links to Amazon for books that are relevant to the subject, click on the appropriate country flag to get more details of the book or to buy it from them.

cover Physics for Game Developers - Assumes a knowledge of vectors, Matrix and trigonometry (the book has a one page introduction to quatnions). The book introduces Newtons laws but it does assume a basic knowledge physics. It covers Kinematics, Force, Kinetics, Collision (detection), Projectiles, Aircraft, Ships, Hovercraft, Cars, Real-time, 2D rigid body, Collision Response, Rigid body rotation, 3D rigid body, multiple bodies in 3D and particles. (I cant find a general formula for collision response which combines linear and rotation, but there may be something in the code included?). If you don't have the prerequisite knowledge of Matrices etc. you may want to get the Mathematics for 3D Game programming book first.
