Magnetic fields are sometimes denoted with B instead of H. This is especially true in NMR Spectroscopy and i think that is what my old E & M books use as well, something like F = E x B. David E. Volk 09:49, 20 May 2008 (CDT)

Yes, I know that people use it interchangeably, but strictly speaking B (magnetic induction) is not the same as H. The magnetization of the medium depending on permeability tensor makes the difference. I plan to write about B soon. I don't know what you mean by F = E x B, is it the propagation vector of an electromagnetic wave?--Paul Wormer 10:47, 20 May 2008 (CDT)
