The invention provides a planar Halbach permanent magnet array, and a method for optimizing an adsorption structure magnetic circuit under a finite volume. A plurality of groups of magnets arranged in a periodic array are arranged in the length and width directions of the planar Halbach permanent magnet array, and each period comprises two first magnets and a second magnet, the NS of each first magnet is in the vertical direction and is perpendicular to each other, and the NS of each second magnet is in the horizontal direction and is arranged between the two first magnets; and gaps are formed between the adjacent second magnets in the same direction. The method comprises the following steps: 1) firstly, establishing a magnetic circuit model of the planar Halbach permanent magnet array; 2) determining design parameters of a magnetic circuit; 3) using Maxwell software parameterized simulation to determine the value range of each parameter under a fixed size; 4) determining primary and secondary influences of each parameter on each index by using an orthogonal experiment, and finally determining a design scheme; and 5) verifying the magnetic adsorption effect of the design scheme. According to the method, the adsorption unit with the limited structure size is optimized, and theoretical modeling of the adsorption capacity of the complex magnetic circuit is simple and has universality.
