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.
