Toroidal coils are used in a broad range of applications, such as high-frequency...
, a type of electrical device - Toroidal and poloidalToroidal and poloidalThe earliest use of these terms cited by the Oxford English Dictionary is by Walter M. Elsasser in the context of the generation of the Earth's magnetic field by currents in the core, with "toroidal" being parallel to lines of latitude and "poloidal" being in the direction of the magnetic field...

- Toroidal coordinatesToroidal coordinatesToroidal coordinates are a three-dimensional orthogonal coordinate system that results from rotating the two-dimensional bipolar coordinate system about the axis that separates its two foci. Thus, the two foci F_1 and F_2 in bipolar coordinates become a ring of radius a in the xy plane of the...

- Toroidal graphToroidal graphIn mathematics, a graph G is toroidal if it can be embedded on the torus. In other words, the graph's vertices can be placed on a torus such that no edges cross...
, a graph whose vertices can be placed on a torus such that no edges cross - Toroidal reflectorToroidal reflectorA toroidal mirror is a form of parabolic reflector which has a different focal distance depending on the angle of the mirror. The curvature is actually that of an elliptic paraboloid with a \ne b. If the shape were that of a toroid, the mirror would exhibit spherical aberration.Toroidal mirrors...

If the network is one-dimensional, and the chain of nodes is connected to...
, known as a toroidal network when an n-dimensional grid network is connected circularly in more than one dimension
