In this second paper the author again considers the slow steady motion of a viscid and electrical conducting fluid, in a moving spherical rigid envelope, plunged in a uniform magnetic field. First he shows that the velocity of the fluid particles verifies the same differential equation of the fourth order witch is satisfied by the vortex vector and the conductive current. After he attends to determine the velocity of the fluid particles and the inducted magnetic field in a point within the sphere when theirs values are however assigned on the surface.
