Equatrons are derived/or predrcting the change m the vapour pressure curves o/oxygen, nitrogen and argon m the presence ol h~gh magnetrc fields. The G~bbs energies of the vapour and hquid phases are equated, thus producing a 'magnetic Clausius Clapeyrnn' equatton. The theoretical results are compared with experimental data measured at helds up to 9.5 x I06 Am ~, using a specially desrgned cryostat and sample holder.
It was found that the effects on the vapour pressure curves o/ mtrogen and argon were insignificant at any field strength. For oxygen, the effect was small and only accurately measureable at very htgh helds. The agreement between the theoretical and practical results was good.
