Energy density made by six rings of current in a box.

This code generates an energy density in the XY plane, made by six rings of current in a box. The plane is half of a meter around the ring structure centered at the dead center. The energy density is entirely driven by the magnetic field. Unfortunately, you need lots of contours (~1,000) to get a detailed map. You will also need to enter the amount of values between the labels (~hundreds). This can take multiple minutes (~10 min) to run. There are some ring values already entered into the program, these are:

- The rings have a radius of: 0.127 meters
- The rings are located: 0.1963 meters from the center
- The rings have: 20000 AmpTurns

You will also need to enter three values into the code, these are listed below:

Number of Cells?: 40
Number of Contours?: 1000
Value between labels?: 300
