In all experiments rotate the 3D projection and study the movement
under different angles of view.

E 1: Start with the default setting and add a positive or negative velocity component vx with its slider. Try to keep the particle within the range of view by operating the slider. Try to stabilize the particle;  What is the proper value of vx?

E 2: After reset add an electric field Ex. Try to stabilize the path by adjusting Ex. What is the difference to E1?

E 3: After reset draw the particle to some other point and repeat the experiments E1 and E2. Explain the result.

E 4: Try the same experiment for different axis orientations of the screw. Set proper vector components after reset and then press start.

E 5: Add other magnetic field components and analyze the result.

E 6: After reset add an electric field component perpendicular to the magnetic field and start. In which direction seems the axis of revolution to move? Why?

E 7: Define arbitrary vectors and try to interpret the results.
