During our Week 2 Lecture, it was clarified that liberties should be taken with this project and that each group should think with the idea of creativity. We were also introduced to the idea that Python can be used as a programming language, rather than MATLAB.
The class was shown of the issues we might be facing by using some of the strongest magnets commercially available: their electronic field and how they will disturb electronics near by. This gave us an issue to consider and another design constraint to incorporate:

Not only does the strong magnet have an electronic field, but the small magnet inside the gel does too. The magnetic field of the small magnet may cause it to experience torque from friction and attraction/repulsion:

We were also introduced to the possibility of using an electric coil to create a magnetic field, rather than a strong permanent magnet (having the benefit of controlling the strength and activity of magnetic/electronic field):
