The invention discloses a method for utilizing element coils to carry out shimming on a Holbach magnetic body. The method comprises the steps of: according to the structure of the Holbach magnetic body, uniformly distributing the element coils respectively at regular intervals in the axial direction, at regular intervals in the angular directions and at regular angles; matching an independent drive circuit for each element coil, wherein power supply currents are mutually independent; or dividing the element coils into a plurality of sets, and applying the same drive current to each set of element coils; and according to the non-uniform magnetic field distribution required to be generated, calculating the current distribution direction and magnitude in each element coil. By adopting the method for utilizing the element coils to carry out shimming on the Holbach magnetic body, the uniformity of a magnetic field is rapidly and conveniently adjusted, a shimming effect capable of counteracting the uniform magnetic field is realized, the space occupied by the shimming coils is reduced, and the size of a measuring aperture is increased.
