		| Abstract: | 
		Two fundamental MHD problems in solar physics are discussed. The first one is the so-called Parker problem, namely the behavior of magnetic fields when their fieldline footpoints are moved around by flows. The expected incapability of settling the field into static equilibrium is a theoretical basis for the microflare model of coronal heating. The second one is the so-called Aly-Sturrock conjecture, stating that the magnetic field stressed by footpoint motions attains energy but may never exceed the energy of the open field. This is thought to be an anti-CME theorem. |
