Magnet dimensions

Here's another one: On the HiAmp versions of the Lehners the windings are visible. The wires ar the back are the actual windings, just like with Feigaos. Now, the higher turns have much thinner windings (the bundle is thinnner) than the lower turns. Why is that?? And has this an influence to the torque?

Thank you
