  Due to the resemblance between Maxwell and the gravitomagnetic equations
obtained in the weak field and slow motion limit of General Relativity, one can
ask if it is possible to amplify a seed intrinsic rotation or spin motion by a
gravitomagetic dynamo, in analogy with the well-known dynamo effect. Using the
Galilean limits of the gravitomagnetic equations, the answer to this question
is negative, due to the fact that a "magnetic" Galilean limit for the
gravitomagnetic equations is physically inconsistent.
