Effect of conductivity on Dipole Magnitude and Orientation. Effect of anisotropy on dipole vector (left) magnitude and (right) direction. The conductivity in the fibre direction was maintained at 0.4 mS mm^-1, while the conductivity in the sheet and sheet-normal directions was varied between 0.4 mS mm^-1 and 0.004 mS mm^-1. The maxima for each problem is denoted by M1 and M2 in (right), with the solid black arrow indicating the direction of the movement of the dipole heads.
