The invention discloses a magnetic field imaging device for magnetic material detection. The magnetic field imaging device is provided with a linear array sensor, wherein a plurality of detection units are arranged side by side; the sensor is mounted on a linear motion module and is driven by the linear motion module to move, so that magnetic field data detection of each area of a detected magnetic material is realized. Detection data is sent to an upper computer after being primarily processed by the signal processing and control device, and the upper computer processes a digital signal to obtain a magnetic field image of the to-be-detected magnet and stores magnetic measurement information of the to-be-detected magnet. According to the invention, rapid acquisition, data processing and real-time imaging of the magnetic field information of the magnetic field material are realized, and the detection efficiency and the data processing efficiency are greatly improved. 本发明公开一种面向于磁性材料检测的磁场成像装置，设计有多个检测单元并排设置的线性阵列传
