Fields lines from a point charge.

Visualization

Don't just tell them, show them.

A Positive Charge Surrounded By A Gaussian Sphere

The field lines radiate out from the charge and pass through the sphere.

Mouse Interactions
  • Click and drag with the left mouse button to rotate the model around the x and y-axes.
  • Shift-click with the left mouse button to rotate the model around the z-axis.
  • Use the mouse wheel to zoom in and out.
Touch Interactions
  • Swipe with a finger to rotate the model around the x and y-axes.
  • Rotate or twist with two fingers to rotate the model around the z-axis.
  • Pinch with two fingers to zoom in and out.

Easy To Teach

Check out our catalog of prepared visualizations, and see their use in integrated lessons.

// Lookup the HTML5 canvas
c      = document.getElementById('c');
// Draws electric fields
render = new fieldRenderer(c);
// A +1 charge at the origin
charge = new Charge(1.0,0.0,0.0,0.0);
// Add it to the things to be drawn
render = renderer.addCharge(charge);
// Start drawing
render.start();

Easy To Customize

The toolkit used to create the catalog is a well documented project.
