After experimenting with the simulation, your task is to complete a discussion post summarizing any observations or questions you have may have. Here are some suggestions for conversation starters:

• What was this exercise simulating?
• What did you notice about the field strength as you moved away from the blue/red fields?
• What happened when red and blue fields were placed side by each? What happened when two blue fields were placed together?
