It is pointed out that the spin-spin correlation function in a magnetic-polymer model is proportional to the generating function of the probability function describing the spatial distribution of monomers. This observation is used to generalize Thorpe's study of a freely jointed magnetic polymer, to take the excluded-volume effect into account using a scaling theory. The inverse magnetic correlation length measured along the polymer plays the role of a scaling field which can, therefore, be controlled experimentally. However, strong disorder in the magnetic coupling can prevent this field from reaching its critical value, zero.
