Because the tire is actually a toroid (a circular tube) rather than a straight cylinder, the ply cords actually lie approximately 11 degrees off the perpendicular.

Encyclopedia Britannica

This factor is typically given by the ratio of the circumference of the toroid to the gap in the ferromagnetic material.

Encyclopedia Britannica

The magnetic field inside a toroidal winding similar to the one illustrated in Figure 10 but without the iron ring is given by B = μ0Ni/2πr, where r is the distance from the axis of the toroid, N is the number of turns, and i is the current in the wire.

Encyclopedia Britannica

If the gap is 1 cm wide, the field in that gap is about 0.12 tesla, a 60-fold increase relative to the 0.002-tesla 0.002-teslae toroid when no iron is used.

Encyclopedia Britannica

If the same toroid is wound around an iron ring with no gap, the magnetic field inside the iron is larger by a factor equal to μ/μ0, where μ is the magnetic permeability of the iron.

Encyclopedia Britannica

The impeller sucks air into the base and propels it up into the ring-shaped, or toroid, head of the fan.

Best practice

Use "toroid" when precision is needed in describing a shape, especially in scientific or engineering contexts. Alternatives such as "ring-shaped" may lack the necessary specificity.

Common error

Avoid using "toroid" interchangeably with terms like "circle" or "cylinder". A "toroid" is a three-dimensional shape formed by rotating a circle around an axis external to the circle. Using similar words might make it hard to fully understand its 3D form.

Linguistic Context

The primary grammatical function of "toroid" is as a noun, referring to a specific geometric shape. As confirmed by Ludwig, this term accurately describes a surface of revolution generated by rotating a closed curve about an axis.
