This fact lies at the basis of the design of magnetic confinement devices. | This fact lies at the basis of the design of magnetic confinement devices. | ||
If a single vector field ''B'' has several such toroidal flux surfaces, they must necessarily be ''nested''. It then makes sense to use the function ''f'' to label the flux surfaces, so ''f'' may be used as an effective "radial" coordinate. The toroidal surface | If a single vector field ''B'' has several such toroidal flux surfaces, they must necessarily be ''nested''. It then makes sense to use the function ''f'' to label the flux surfaces, so ''f'' may be used as an effective "radial" coordinate. The toroidal surface enclosing a volume of zero size is the ''toroidal axis'' (called ''magnetic axis'' when ''B'' is a magnetic field). | ||
