1. A system for pumping a fluid, said system comprising:
a pump comprising:
an inlet and an outlet for respectively introducing and extracting said fluid capable of being pumped,
a flexible membrane having two opposite surfaces, said membrane comprising a spatially rotating permanent magnetization structure,
a rigid support means on which is fixed at least part of one of said surfaces of said membrane,
a source of a magnetic field capable of generating a driving magnetic field at the place where said membrane is located, said driving magnetic field having a substantially homogeneous orientation, said membrane being capable to deform, under the effect of said driving magnetic field, according to a ripple having alternately one or more concave parts and one or more convex parts, the ripple being able to move under the effect of said driving magnetic field, said fluid capable of being pumped between said inlet and said outlet being located at least between one of said surfaces of said membrane and said rigid support means.
