The utility model relates to a fluid magnetization test device. The fluid magnetization test device comprises a feeding pipe, an air inlet pipe, a magnetizer and a discharging pipe, and is characterized in that the magnetizer consists of a plurality of permanent magnets in parallel connection. The magnetizer is selected from permanent magnets universal in market, and may be a natural magnet or man-made magnetic steel. The fluid magnetization test device provided by the utility model is simple in structure, low in cost, efficient and convenient in operation, and suitable for cold-state and hot-state fluid magnetization experiment. The fluid magnetization test device can carry out magnetization experiments under different magnetic intensities at the same time by reasonably arranging the magnetizer and pipes, and is convenient in simultaneously carrying out magnetization experiment of two fluids with different properties.
