I'm guessing that you have either made and tested a rodin coil and decided that there's no difference from any other electromagnet..
OR
You googled rodin coil and saw the weird rabbit hole that the rodin coil is involved with.
I have seen three different designs claiming to be rodin coils. Each of them has different magnetic fields, with different shapes and strengths. I thought I might try building one and playing with the magnetic field, just for fun. I bought an arduino board and a bunch of hall effect sensors. I wanted to make a project to learn programming and physics with my kids. Thought maybe I could use a rodin coil as the primary or secondary of a tesla coil, or maybe as the toroid? Maybe there is another application that rodin coils would work, such as speaker magnets or generator coils...
