Dear Samuele Martinelli ,

That’s ok, but you don’t need to go through the CGS system of units. Directly from the SI equation B=mu_0 (H+M):

as 1 V.s/m2 = 1 T, then #T/mu_0=#(A/m), and taking into account that mu_0=4 pi 10^-7, you get: #T 10^7 / (4 pi) = # (A/m).

Thank you for your answer Jose-Miguel Garcia-Martin ,

So I was doing everything correctly, the only problem is that I get really high magnetization value (only for the first point at 0.03125 T I would get 1989436789 A/m) and if I use the SI equation that you wrote my H value is negative, and also really big (-1989188109 A/m). Should I take it as an absolute value? And is not odd that it is such a big value (when I reach saturation in the BH curve it will even be bigger of course)?

I mean, I think I got everything else correct since in the axis of the plot I took the value 2.5 Vs/m2 and the label axis's name is "Magnetization x 1000 (Vs/m2)", so it should be indeed 2500 Vs/m2.

It reaches magnetic saturation at 13500 Vs/m2 then.

No, you have to divide by 1000 then, or by the multiplying factor that appears in the axis ! As I said before, 1 Vs/m2 = 1 T and obviously your axis is not 2500 T but 2.5 T !

Oh right, I was understanding bad the axis, Thank you so much!

However, I would still get a negative value from the formula 10^7/4PI, my H would be -1964568.829 A/m
