| Jul 26, 2014 at 11:54 | comment | added | Robert Seifert | That would mean $\Delta R = \frac{R}{N} ~\rightarrow ~ \Delta R = \frac{R-\epsilon}{N}$ and $r ~\rightarrow ~ r + \epsilon$ - if you insert that into my formular you won't get much of a change. It is basically right, that the magnetic flux goes to infinity at the origin. That's why you can't calculate that geometry with field theory or even basic relations involving $\Phi$, $B$ or $H$-Fields. For static fields the reluctance should be constant along every flux path. | |

| Jul 25, 2014 at 11:53 | comment | added | Robert Seifert | As I understand you're suggesting what I have tried. But the resulting series does not converge. | |
| Jul 24, 2014 at 17:05 | comment | added | Robert Seifert | $N$ is the number of divisions: $Ae = A/N$ | |

| Jul 24, 2014 at 16:37 | comment | added | Robert Seifert | I tried it the way you suggested (see my edited question) - but it is a little weird that I just get results as expected for small $N$, so guite big partitions, but not for large $N$. Do you see a reason for that? Is this the way you thought about? | |
