Helmholtz Coils
written by Fu-Kwun Hwang and Wolfgang Christian
edited by Robert Mohr
The EJS Helmholtz Coils Model shows a the magnetic field between two circular coils of wire.  The default configuration, known as a Helmholtz coil, sets the separation distance D equal to the coil radius R.  These values produce a nearly uniform magnetic field B between the coils

The Helmholtz Coils Model was created using the Easy Java Simulations (Ejs) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.  Double clicking the ejs_ntnu_em_HelmholtzCoils.jar file will run the program if Java is installed.

Please note that this resource requires at least version 1.5 of Java (JRE).
