The invention discloses a preparation method of a ferrite magnetic material for a multilayer chip inductor. The preparation method comprises steps as follows: (1) presintering; (2) primary grinding; (3) material mixing; (4) secondary grinding; (5) drying and sintering; (6) tertiary grinding. The preparation method of the ferrite magnetic material for the multilayer chip inductor is simple and convenient to operate and easy to realize, the ferrite magnetic material sintered and formed at low temperature (under 900 DEG C) has excellent magnetic conductance performance, lower specific resistance and lower dielectric loss performance due to scientific formula design and a reasonable sintering process, the comprehensive electromagnetic performance is excellent, and the preparation method has wide application prospect in the field of the multilayer chip inductors.
