Sudden Change in Velocity shows the effect of a sudden change in velocity on the electric field vectors and magnetic field lines (in the xy plane) associated with a positively charged particle.
Watch the animations, varying the velocity and sudden change in velocity of the point charge. The animation takes one time step to calculate the proper field vectors and field lines for the point charge.
~~1. Describe the electric field vectors and magnetic field lines before, during, and after the velocity change.
~~2. The draw the electric field lines from the electric field vectors. What do you notice about these lines before, during, and after the velocity change?
~~3. Qualitatively, is there radiation during the animations? If so, when?
