Hello,
I'm designing an electromagnet which will simply be a lot of magnet wire wound around a 1/2" diameter steel dowell rod. I've been searching around on the internet unsuccessfully for a while now looking for a general chart which gives permeability data for various materials (Like what you'd see in a physics textbook in the section on permeability, only I don't have a physics textbook at hand). I don't expect to be able to find the exact permeability for the steel that I have--If I could find something that said "steel : xxx N/A^2" I'm sure that ballpark would be good enough.
Thanks!
The one table I have shows iron, in various forms, with maximum permeabilities from 130 to over 800,000 (1.3 E 2 to 8 E 5) - that's a huge range. Sorry I don't have anything better.
Thanks for the quick response.
I don't know why I didn't check there first, but Wikipedia has an article for Permeability (electromagnetism) which has a generic steel spec like I was looking for. It gives it at 875 E -6 Newtons/Amp^2. I know what the huge numbers you have are, the relative permeability, which is what you multiply the permeability of free space by to get the material's permeability.
Thanks again!
