This question asks if the comparatively large paramagnetic susceptibility of liquid oxygen (LOX) is considered when designing rocket tank and engine systems. This comment suggests fuels such as RP-1 (kerosene-like) and liquid hydrogen (often used in liquid-propellant rockets) do not have a susceptibility as large.
I'd like to find either the approximate or even ballpark values for the magnetic susceptibility of the following four materials, or at least a source where they might be found:
I have tried google searches of various permutations of terms, but so far no luck beyond the one value I was able to cite in that question (LOX susceptibility here).
I'm fairly sure that the susceptibility of the other three are much smaller (100× or more) than that of LOX. For example here is what I can do now:
- LOX: use the value reported in the link above; 3.5E-03
- LH2: This question links to this table which lists the susceptibility of liquid hydrogen -5.44E-06 cm³/mol. If I use a density of 0.07 g/cm³ and molar mass of 2.0 g/mol (both from here) I get approximately -1.9E-07.
- RP-1: decide that for paramagnetic and diamagnetic susceptibility, kerosene and crude oil are very roughly equivalent and use -1E-08 m³/kg from section I of this along with a density of order of magnitude 1000 kg/m³ to get a susceptibility of roughly -1E-05
- LNG: - same argument as RP-1, roughly -1E-05
