Methods and apparatus for compressing a lower strength magnetic field to produce high flux densities, such as about one megagauss, employing a hollow, rotating, electrically conductive liquid liner to trap the magnetic flux, and in which the rotating liner is magnetically forced to implode. Energy to drive the implosion is derived from the rotational energy of the liner. Energy may be recovered subsequently as rotational energy upon expansion or rebound of the liner.

Apparatus for compressing a magnetic field to provide a region of high magnetic flux density, comprising an electrically conductive liquid liner, induction motor stator means for confining said liner and for providing a rotating stator multipolar magnetic field to inductively rotate said electrically conductive liner at a predetermined rotational velocity and to produce a multipolar rotor magnetic field substantially synchronously rotating with said liner and said stator field in a conductive outer surface of said rotating liner, said liquid liner having a volume less than the volume of said stator means such that upon rotation of said liquid liner by said stator means, said liner forms a thick rotating liner body having a cylindrical electrically conductive inner surface, means for providing an axial magnetic field longitudinally of the axis of rotation of said stator field, means for abruptly stopping the rotation of said stator field to provide a stationary stator field and for abruptly converting kinetic rotational energy of said liner means to implosive kinetic energy through repulsive interaction of said stationary multipolar stator field and said rotating multipolar rotor magnetic field to compress said liner and abruptly reduce the radius of said inner surface and to compress said axial magnetic field by interaction thereof with said conductive inner surface, and means for reinitiating the rotation of said multipolar stator field in phased relationship with said rotating multipolar rotor field of said liquid liner such that upon expansion of said compressed liner, outward radial expansion energy of said liquid liner is converted to rotational kinetic energy of said liner to rotationally reaccelerate said liquid liner.
