The present invention provides an apparatus for rapid solidification of liquid in a magnetic field and an anisotropic rare earth permanent magnet. The apparatus for rapid solidification of liquid in a magnetic field includes a magnetic circuit which provides a magnetic field of at least 1 T to a quenching part and produces a quenching thin strip in the magnetic field. The apparatus for rapid solidification of liquid in a magnetic field produces the quenching thin strip by quenching an exchange-spring magnet having an inner structure in which a hard magnetic phase and a soft magnetic phase are finely dispersed. Easy magnetization axes of the hard magnetic phase inside the quenching thin strip are aligned in one direction. The anisotropic rare earth permanent magnet includes the quenching thin strip.COPYRIGHT KIPO 2014
