The Anomalous Magnetization of Iron and Steel, B. Osgood Peirce 1912: https://www.jstor.org/stable/20022770?seq=2
The effects seem to pertain to high dv/dt impulses however.. not to mention antique metallurgical samples (the high-Sv kind). Modern electrical steels OTOH are designed to be high-mu, high-freq and hence low-Sv inductors with minimal remanence / retentivity. Anomalous self-induction must be arising under some very a-typical circumstances if no one's noticed it previously.. and we're not talking micro-teslas here, he's claiming a 400 - 500% gain in flux density, sufficient to turn a gennie.. The claim seems eminently falsifiable though, reducing to this singular putative exploit - whatever the specific grade of material he's sourcing will have a B/H graph in its spec sheet, since this is its whole raison d'etre, the very properties it's designed and purposed for. So, find out exactly which material it is, download the spec sheet, and check for a sudden 500% jump halfway up the B/H plot that nobody else but this genius PhD has noticed for some reason, square in the middle of its designed operating range there. Job done, next..
