Pirate - did you get my email? 

Kindest regards,

Based on some reading i have done on old iron , the impurity found in the iron was phosphor ( based on research on vintage piano string composition ) .

But the main issue is that iron is not steel but steel is iron , we need the unhardened stuff , steel will remain magnetized. But i have given up finding some , even some core stolen electromagnets show clear residual magnetism (compass test).

My conclusions is that waiting on the optimum core , is lost time working on the prototype .

Hello Mark.  If you're really anxious to use pure iron - perhaps you could get piping? and fill it with iron filings.  I've done that but am not sure whether it's going to work or not - not yet anyway - as I haven't finished the winding.  Hopefully I'll get back to this in a week or so.

Iota - I was really, really way out in that previous post of mine.  I've been doing some reading and will try and get my thoughts together later on today - if possible.  Else I'll need to defer it for tomorrow.  I'm strill struggling with the electron 'drift' as I can't find any examples where the electron change doesn't resolve itself into the orbitals of some kind of atomic structure.  But I'm still looking. 

Regards
Rosemary

Your right about the iron. If your electromagnet core is laminated electrical steel you should have negligible remanence. Ive never seen any on my monitor after they have been in contact with very strong neos and other magnets. I have 2 compasses. One has a brass casing and the other plastic. I get some movement on these cores with the brass casing but not the plastic. Make sure you dont magnetize your compass needle also.
Ns didnt have the materiels we have today. Im still thinking his core was 1018 steel. I get a very slight remanence with 1018 steel. Lasers core is better than that. You just dont get the field collapse intensity with higher carbon materiels. A laminated electrical steel core would be the cats meow but not necessary for a prototype.

Take a tip from this Vietnam veteran. Never ever give up! My nephew who has a Phd in physics and a degree in Computer science can attest to that.

Iota:

This is why I believe a ferrite rod would make a perfect core for these.  It should be able to magnetize/de-magnetize very fast as in our JT circuits.  Stubblefield, of course, did not have access to these but, in my opinion, if he did, he probably would have used it.

Thanks for your service in Nam.
