Does anyone have any quantitative data on how annealing affects permeability for low carbon steels? Perhaps some B-H curves before and after annealing? I'd like to get an idea of how much is to be gained by annealing.
I have a solenoid electromagnet whose cylindrical steel core protrudes out and has a chamfer at the end. When the core end contacts the mating part, the chamfer reduces the actual contact area by 1/2 (compared to the core diameter). I know pull force is dependent on core diameter, but is it...
