B and H
Authors are sloppy about the use of B and H. It appears that serious calculations of magnetic susceptibilities, Kubler for example use H and find it self-consistently inside the material. Because it is a self-consistent calculation, and so involves adjustable parameters, it is moot what the exact interpretation of H may be, but M = χH with χ dimensionless makes H the way to go. The only role left to B is outside the material where B = μ0H because M = 0, and then the role of B is just to establish the external applied H. John R. Brews 16:44, 13 December 2010 (UTC)
