This paper presents some reflexions about the theory of magnetic spinning alignment. It is shown that a classical enhanced thermal Davis and Greenstein mechanism may be considered as a limiting case of Purcell's suprathermal spinning alignment theory when the number of active sites on a given grain becomes very important and/or for very short-lived suprathermal sites.

This result is applied to the interstellar medium and some problems in which it may be important are briefly discussed, with special attention to local implications.
