This plot jumps right to the conclusion and shows shear force with increasing magnet thickness along the x-axis. Starting at about 2 mm, we begin to see very diminishing returns in terms of shear force vs. increasing magnet thickness. To be determined is the tradeoff between the PM's contribution and the relative increase from
## 2) Is there a penalty to having a large insulator (which creates a high reluctance gap) between your motor steel and winding? Is it optimal to ensure that your winding is wrapped tightly against the inductor?**

* H field produced is defined as the product of amps flowing through a winding and number of turns in that winding.
* Having a larger diameter coil increases the resistance of the winding, so perhaps the tradeoff is that we are creating a lot of flux that doesn't get used or gets canceled because there are more windings in the way.
* If you have a small steel core at the center of a large diameter of windings are you being punished?
## 3) What is the effect of filling an air core winding to the core with windings? Diminishing returns? Higher peak flux at center but lower exterior? Would an optimal coil have the smallest possible wall thickness?**

* This would be a good one for FEA generally, but there's difficulty in that the ID increasing must effectively mean fewer coils, so it's necessary to compensate for both.
