    The invention discloses a device for simulating a fluid microgravity environment by using a magnetic compensation method. The device for simulating the fluid microgravity environment by using the magnetic compensation method comprises a pair of external coils, a pair of internal coils, a non-magnetic stainless steel L-shaped folding plate, a main body bracket, an x-y-z three-axis displacement platform, a dynamometer, a locating concentric circular plate, a first excitation power supply, a second excitation power supply, a constant temperature water groove, a square-section hollow red copper wire, a cooling water busbar and a cooling water pipe joint. According to the device for simulating the fluid microgravity environment by using the magnetic compensation method, by using a composite magnetic field of an uniform magnetic field and an uniform gradient magnetic field which are correspondingly generated by the internal and external pairs of electromagnetic coils, a magnetic field forcereverse to the gravity force is applied to magnetic fluids in the central positions of the coils, wherein the uniform magnetic field enables the magnetic fluid to reach a saturated magnetization state, and the uniform gradient magnetic field enables any point in the magnetic fluid to receive the magnetic field force, whose direction reverse to the gravity force direction, so that the magnetic fluid reaches a microgravity state. The device for simulating the fluid microgravity environment by using the magnetic compensation method has the advantages of lower experiment cost, long maintenance time and controlled stability.
