I've been reading good things about Neodymium as a magnet material, namely that it has some of the desirable properties of Alnico (such as low flux modulation) at a much lower cost.

Now from what I gather reading some of the dialogue between Earl Geddes and Wayne Parham, one of the nice things about Alnico is that it's conductive, so that in effect it is its own "shorting ring".

Does Neodymium have this self-shorting properly like Alnico? Or, in order to approach the low distortion performance of say a JBL driver, would a Neo driver need its own shorting ring?

Thanks!
