There is disclosed an apparatus for generating gravitational force/gravitational field, which, for example, may be used in space and avionics applications, said apparatus comprising a capacito-inductor, constituted by at least two coils, made of two metal layers with two dielectric layers provided therebetween, said coils being wound in predetermined turns on a cylindrical core of an insulating material; a magnet placed at the center of said capacito-inductor for creating and passing radial magnetic field through the capacito-inductor; power supplies for applying equal and opposite current pulses at the end terminals of said two metal layers of the capacito-inductor, and also for applying predetermined voltage between the same end terminals of said metal layers; and a drive source for rotating the capacito-inductor, journalled between two covers. Also disclosed a method of generating gravitational force/field by using said capacito-inductor
