The present application relates to the technical field of
biological effect test equipment, and particularly relates to a spatial
magnetic field generating device for biological sample test, which comprises a rack, a driving unit arranged on the rack, a
magnet assembly rotating driven by the driving unit, and a
control system electrically connected with the driving unit, wherein the
magnet assembly comprises at least one pair of N-S pole oppositely arranged permanent magnets; the device further comprises a magnetic shielding cover arranged between the driving unit and the
magnet assembly. The present application effectively suppresses the
eddy current induced by the high-speed rotating permanent magnet in the
metal part by introducing the magnetic shielding cover, thereby significantly reducing the operation heat of the device, solving the problem that the stability of the equipment and the environment of the biological sample are affected due to the excessively high temperature rise during long-term continuous work, and simultaneously improving the
mechanical stability and the heat dissipation efficiency of the device at high speed through the high-precision
dynamic balance calibration and the optimized heat dissipation hole design, so as to provide a more reliable and pure
magnetic field environment for
biological test.
