Howdy Ed,
I was researching the process for anealing 1018, and came upon your post of 25 Sept 09.

If this is a DC application who would care about the perm?
Saturation is all that matters.
Any low carbon steel grade with less than 0.2%C that has been annealed at 1400-1475F...
While researching electromagnet construction, I tried to find information about the feasibility of using laminated core (transformer core) as the core for a DC magnet.
The only thing I could find was an opinion that the laminations would not be as efficient as a solid core due to the air gaps...
Howdy, new guy here,
I tried posting this earlier today, but it didn't seem tp go through, so I'll try again.
We are re-purposing an old transformer to use as a magneto magnetizer.
We started with a transformer that has a two piece armature. The bottom was one piece, in the shape of an I, 1.75...
