Toroids have less audible noise, such as mains hum, because the magnetic forces do not exert bending moment on the core.

A restricted class of Stewart toroids, also defined by Stewart, are the " quasi-convex toroidal polyhedra ".
43.
The sun-ghosts use toroids to arrest the ship's fall, but eventually they give out, and the ship plummets.
44.
Core uses tiny magnetic toroids ( rings ), the " cores ", through which wires are threaded to write and read information.
45.
There is also a larger opaque toroid extending several parsecs from the central black hole, containing a hot gas with embedded regions of higher density.
46.
In mathematics, a "'toroid "'is a surface of revolution with a hole in the middle, like a doughnut.
47.
Sitting in the middle of the toroid was a large iron core from a transformer, which was used to induce the current into the gas.
48.
Each toroid works as a stage during the rocket climb once it has been ignited from around 30 km ( 19 mi ) above ground level.
49.
For example, the one-holed toroid and the Klein bottle both have ? = 0, with the first being orientable and the other not.
50.
The idea appears to have been to create compact toroids of high-density plasma that would be ejected from the device using a massive magnetic pulse.
