Assuming the flux surfaces have this toroidal topology, the function ''f'' defines a set of ''nested'' surfaces, so it makes sense to use this function to label the flux surfaces, i.e., ''f'' may be used as an effective "radial" coordinate. Each toroidal surface ''f'' encloses a volume ''V(f)''. | |||
