    "abstract": "A new criterion for pressure-driven interchange instabilities in cylindrical\ngeometry is derived, based on an alternate use of the Energy Principle. This\ncriterion is inequivalent to Suydam\u0027s criterion and does not contain the\nmagnetic shear. In fact, it is shown that Suydam\u0027s criterion relates to the\ninstability of the slow magnetosonic branch, while the present criterion\nrelates to the Alfv\\\u0027enic one, which is the most dangerous of the two. These\nfindings explain why pressure-driven modes nearly always exist even if Suydam\u0027s\ncriterion is satisfied by a large margin.",
