Abstract
Static shapes of the magnetic fluid surface in non-uniform magnetic fields are studied theoretically. In particular, the case when the magnetic fluid volume can fill the space between non-magnetic surfaces is addressed. Two typical non-uniform field geometries with spherical and cylindrical symmetries are analyzed, i.e. the field of a magnetizable sphere exposed to a uniform magnetic field and the field of a straight current-carrying wire.
