We present new regularity criteria in terms of the negative part of the pressure p or the positive part of the extended Bernoulli pressure [Formula presented], where u is the velocity, and b is the magnetic field. The criteria extend the previously known results, and the extension is enabled by the use of an appropriate Orlicz norm.
