Resumen
The vector potentialsA( r) produced by spherical, cylindrical, and elipsoidal uniform superficial distributions of electrical charge rotating at a constant angular velocity\ω, are found. This is done by modeling such a distributions as if they were simple bobbins made of N loops of a very thin coil carrying a current I and calculating simply the dipolar potentialA \text dip( r) produced by them. Due that in the case of the spherical geometry the potentialA( r) has already been calculated its value is used as a consistence test of the present approach, for the two other geometries the analytical calculation of the potentials is not so trivial by this reason the equalness betweenA \text dip( r) andA( r) is proved trough a numerical evaluation of the complex integrals appearing in the Biot-Savart expression forA( r). The respective magnetic fields generated by these three rotating distributions have an identical structure: they are constant inside the surfaces while outside them they are dipolar-like (nearby to radiation zone). An application of the above results to quark confinement inside hadrons is proposed.
