Bio Electric Field

This interactive simulation allows students to explore the concept of electric field in a 2-dimensional situation. Users can place one to five charged particles on the field and move a test charge around the plane. A grid of field vectors can also be activated to show the direction of the...

The Point Charge Electric Field Demo model shows the electric field with multiple point charge configurations and vector field visualizations. Users can select these configurations from a drop down menu or can create their own configurations. The Point Charge Electric Field Demo model was...

The Point Charge Electric Field in 1D model investigates the electric field at various positions along a line, when there are either one or two charged particles on that line. The electric field is represented in two ways. First, there is a movable positive test charge that you can move along the...
