Toroidal Field

A Vector Field resembling a Torus which is purely circular about the z-Axis of a Sphere (i.e., follows lines of Latitude). A toroidal field takes the form

$${\bf T} = \left[{\matrix{ 0\cr {1\over \sin \theta} {\part... ...ver \partial \theta}\cr}}\right].\hrule width 0pt height 5.5pt$$
