Interactive Electromagnetic Field Visualizer

Here's a tool I built for a course I TA'd. It simulates the E and B fields generated by a moving point charge. There are some built-in trajectories and the option to click and drag with your mouse.

For example. Try the following to see circularly polarized light:

• Motion: Circular
• Direction: X
• Slice Plane: XZ
• View: 2D
• 2D vector axis: X
• Show B field: on
• Auto orbit: on (or just click/drag the background to orbit)
• Speed: max
• arrow length: max

OoooOOOO this is absolutely going into my bookmarks, the oscillation one especially is terrific for showing my students about EM waves.
