Toroidal and poloidal coordinates - Wikipedia
WebToroidal and poloidal coordinates. A diagram depicting the poloidal ( θ) direction, represented by the red arrow, and the toroidal ( ζ or φ) direction, represented by the blue arrow. The terms toroidal and poloidal refer to directions relative to a torus of reference.
Toroidal and poloidal coordinates explained
WebThe terms toroidal and poloidal refer to directions relative to a torus of reference. They describe a three-dimensional coordinate system in which the poloidal direction follows a small circular ring around the surface, while the toroidal direction follows a large circular ring around the torus, encircling the central void.

Torus - Wikipedia
WebIn geometry, a torus ( pl.: tori or toruses) is a surface of revolution generated by revolving a circle in three-dimensional space one full revolution about an axis that is coplanar with the circle. The main types of toruses include ring toruses, horn toruses, and spindle toruses.
Poloidal Definition & Meaning - Merriam-Webster
