Recently, the alignment of magnetic materials （including paramagnetic and anti-magnetic materials） in magnetic field has been concerned widely. The application of anisotropic polymer composite in different fields and its preparation by magnetic induction are reviewed. Meanwhile, the advantages of magnetic inducing orientation are introduced. The orientation mechanism of filler in magnetic field is analyzed from the perspective of the anisotropic susceptibility energy and magnetic torque. The properties of anisotropie composite prepared in magnetic field such as mechanical properties, electrical properties and thermal properties are illustrated. The prospects of preparing anisotropie polymer composite by magnetic induction technology are also reviewed.
