Re: [femm] RE: Find "silicon core iron" material



Attached is a femm file with data for deltamax which is a 50% nickel-iron alloy.

I think you gave me this Dave sometime ago.

Hi, David,

By any chance, do you know the B-H curve of 50% Fe, 50% Nickle, or in
other words, what is permeability of this material?
Thanks!
