Above Left: Biaxial? or tetra- toroid?, also coined poloid , as drawn here has 27 identical loops. Compared with ordinary toroid coil below, the main differences are twisted loops instead of the plain toroid loops and the involuted "donut hole". This 3d model can be built. While 27 closed loops are presented to show a tetrahedron relationship, all loops can be one continuous wire and has been studied for interesting electronic properties.

Above Right: Edge centers of the tetrahedron were used as snap points, (alignments), to "mold" an individual loop, representative of loop in the poloid. The red loop indicates corresponding views of one loop, (in poloid and in tetrahedron mold above- right.) The tetrahedron functioned as a mold in a 3d CAD program: each point or corner was used in a consecutive snap operation while making a closed, quadratic, bezier curve, (or loop). Another way to visualize: grab an "O" ring at two points and twist 90 degrees. Another tetrahedral insight: twisting, bending or warping... Is there a connection to the "hand rule"?, (of electro magnetism, that is).

The plain torus coil above is of the common variety which is used in many electronic products and industry. In addition to a comparison for understanding the poloid, it is also evidently conceivable as a naturally occurring orthogonal field inside the poloid. The drawing to the right only approximates the orthogonal field relationship intuitively.

 

While the model can be built with wire or with the new "3d printing" machines, one point needs clarification. In this particular 3d model, no attempt was made to avoid crossing lines. In real life, this means that the wires would need to weave around each other, which obviously would change the pattern slightly.

 

To Right: Two different models of a poloid have a a common torus place inside, to show the orthogonal field relationship.
