    magnetic standards

    I looked at the information they have input for N35s, and it appears that I was looking at the wrong curves. The up-and-right curve labeled 20C, which is the shape I'm used to seeing for that quadrant of the hysteresis graph, is what I was trying to input. Thanks for the heads-up, I'll go have...

    magnetic standards

    That is helpful information. I have attached the two files I have gotten requesting this information. I tried putting in the information from the graphs, but Maxwell 3d v11.1 said that the curve can't be less than that of empty air, so it wouldn't accept the information I acquired by counting...

    magnetic standards

    Is there a committee that establishes standards for qualifications such as the N42 rating? Are they accessible for finding information that goes with a rating, such as the hysteresis curve for the mentioned N42 rating? If there isn't any official body, where can I get a numerical listing of...

    bismuth

    I'm actually considering the use of bismuth with N35's in Maxwell SV, and you need to define the material to do anything with it. I'll try the straight line and see what happens, although I'm not sure how I'll test the simulation accuracy before building something.

    bismuth

    It doesn't make sense to me, but just in case I'll ask. Is there a demagnetization curve for diamagnetic materials such as bismuth? If there is, can someone please provide the curve or data points to graph my own curve? Thanks,
