A Student's Guide to Maxwell's Equations
3-D Field Models

The twelve sketches of electric and magnetic fields shown in Figures 1.1 and 2.1 in the book are available here as VRML files so you can see the fields in three dimensions.  You’ll need a VRML plug-in for your Web browser to view these files. Several free 3D viewers are available on the Web, such as Cortona®.
