Magnetic field magnitude distribution inside toroidal flux ropes (their circular cross sections) with the Tsuji (T), Miller & Turner (MT), and modified Miller & Turner (mMT) solutions (magnitude is scaled by the maximum value B_max inside a corresponding rope; the position of B_max shows the bullet). The ovals are magnetic surfaces (more precisely, their xz cross sections) and the symbols “+” indicate geometric centers of the ropes. Two columns are plotted for two aspect ratios, 2 (left) and 1.2 (right).
