- adj. of or relating to or shaped like a toroid; doughnut shaped
“Toroidal: -- Another type of retardation coil, called the toroidal type due to the fact that its core is a torus formed by winding a continuous length of fine iron wire, is shown in diagram in Fig. 104.”
“The December experiment shows a more or less conventional DC motor with a permanent magnet rotor and a stator wound with toroidal coils; this is an odd choice since toroidal wound coils produce a small external magnetic field and so make very inefficient motors.”
“All of LM's pressurized compartments were spherical, toroidal or cylindrical, including the crew compartment, the forward portion being a wide flat cylinder and the aft being basically cylindrical with cutouts and reinforcement for the hatch on top and the engine on the bottom.”
““Oh, before I go, I can take a wild guess as to how such an impossible feature as that toroidal continuum fold became real.””
““But did she know we were on the wrong side of a toroidal continuum fold?””
““If it were a toroidal continuum fold, that might do the trick . . .””
“Now think about the damage the toroidal continuum fold must be causing.”
“A relatively weak toroidal magnetic field induces spin to control the direction of the axial electron and ion beams, and the B field also maintains ion temps hotter than the electron temps.”
“The most effective magnetic configuration is toroidal, shaped like a thin doughnut, in which the magnetic field is curved around to form a closed loop.”
“There are several types of toroidal confinement systems, the most important being tokamaks, stellarators and reversed field pinch (RFP) devices.”
