The source of the magnetic field is the big question. No doubt that electrons in motion throughout the active material could generate the field, but I ask myself why these electrons happen to be typically moving in the same direction since if they are randomly released by the reaction, their effect would balance out on the large scale. OK, here is a stab at this conundrum. Imagine the “local” or nano conductivity of delocalized electrons, such as happens in graphene. You have heard of “ring current” right? Delocalized electrons, like valence electrons, are not associated with a single atom but are contained within an molecular orbital that extends over several adjacent atoms. “Aromatic ring current” is observed in molecules such as benzene when a magnetic field is directed perpendicular to the plane of the 6 atoms, and a ring current is induced in the delocalized electrons. Same with graphene and even soot. Thus sometimes carbon seems to be magnetic, causing many unsophisticated observers to suggest that carbon has transmuted into iron. LOL, This is a local consequence of Ampere dynamics since the electrons are free to circulate but only in a ring, and they respond much more strongly to the magnetic field then there are rings which are relatively mobile. Ring current is seen with graphene, and of course, CNT can be modeled as a 2D sheet of graphene, wrapped around a hollow mandrel. Now, multiply this effect by S^S - where S is Sagan’s number, and we have the functional equivalent of ferromagnetism in a CNT which is irradiated with SPP. Jones
