For this third piece, I chose the hexahedron or cube. This shape presented a unique opportunity for magnetic motion.
I came up with an arrangement of magnets that allows a hub on each of the modules to slide linear along its axle when rotated 90 degrees. This motion is achieved by bringing the polarity of internal magnets into alignment in such a way that they alternately repel and attract one another.
The motion is not unlike an electric solenoid, but uses only rare earth magnets.
I had originally planned for something simpler but evolution has a way of adding complexity, so who am I to argue.
I try to touch on the wide range of influences that lead to this piece in the video above. The main one being how Joining each of the three sculptures together helped guide the rest of the process.
below are the magnetic arrangements for joining each of the three sculptures in the module series.
