text: what is the effect of an electromagnetic field on hydrocarbon gases? if a hydrocarbon gas is compressed in a container under high pressure and then released into a rubber pipe which goes through an eletromagnetic field, what will be the effect of the electromagnetic field to the hydrocarbon particals? negligible.  the exact effect would depend on the type of field and its intensity, but in any case the effects would be too small to be useful -- or even measurable.
