E1: Start with the default state of 2 particles of opposite polarity. Study the field by rotating the 3D projection with the mouse, and by selection of specific views in the perspective radio button array.

E2: Change arrow length and suppressed levels by their respective sliders and repeat the first experiment.

E3: Draw one of the points with the mouse and observe the change in field. Do this for different perspectives.

E4: Change to equal polarity. Repeat the first experiments and note the difference.

E5: Input a higher and higher number of particles, and compare near field and far field for equal and alternating polarity. Explain the differences.

E6: At n = 100 draw one of the particles out of the ring and move it around. How is the relative change in field with equal and with alternating polarity. Choose equal polarity and increase the number of reduced levels;  compare to 2 particles at a small number of suppressed levels.

E7: Construct interesting arrays of n particles and note their characteristics (cross, square, cube, tetrahedron, hexagon, etc.). Do you find anything exciting?
