Hi,
I am interested in making my own (weak) magnets exposing some ferrous metal to the magnetic field of an electromagnet, but this is theoretical rather than something I am able to actually do right now. I am wondering if there are any formulas that can help calculate/estimate the resulting field strength of the permanent magnet being created. I am guessing the key factors are the strength of the field the ferrous material is exposed to, and the time the material is exposed - but I am not sure how the material qualities might affect the process. Are there any formulas or even rules of thumb that I can use to estimate the permanent magnet's field strength?
Thanks,
Eddie
