A friend just linked me to this video on a new sort of magnet, the polymagnet, which contains custom shaped 3D printed magnetic fields.

Many unique behaviors can be created, such as a "spring" magnet that likes to stay at an equilibrium point above the other magnet. As well, the properties of polymagnets can change as you rotate them in relation to each other.
In theory, a set of spring polymagnets could be made that change their equilibrium point and spring constant when rotated. I propose an adjustable suspension that could be used on an FRC robot using this new tech.
What do the rest of you think about the suspension, and the potential use of polymagnets in FRC in general?
