  1. The most comprehensible modern article I could find so far about neutron star linear molecules is this one. As far as I can understand it, it seems to imply that in a billion gauss field, linear molecules would have about twenty times the tensile strength per weight of steel, and to boost that to a hundred times would take a field of hundreds of billions of gauss. Such substances could remain solid at temperatures approaching a million degrees, or ten million at the higher magnetic field strength. Density would be a few thousand times that of steel at the lower strength, and a hundred times greater still at the higher intensity.

    It might be interesting to calculate the amount of electric current you’d have to circulate around a cylindrical space to maintain linear-molecule conditions inside. I suspect that you’d end up with such a furious mass of rotating electrons that the synchrotron radiation alone would blast anything around it into ruin, and this leakage would require a vast power supply to replenish so the field wouldn’t collapse in a moment. My rough understanding is that to create a billion gauss, each meter of length enclosed by the coil might have to be carrying something like ten trillion ampere-turns. That’s about a kilogram of electrons per second.
