[en] A compact 'warm' magnet with movable poles for a 'frozen' polarized proton target 400mm long and 20mm diameter was described. The gap between the poles is 74 mm, the field in the working volume of the target is 2.5 T with ±1.5x10^-4 nonuniformity. After dynamic pumping of polarization and establishing the working temperature in the target, the magnet poles are put at a distance of 25 cm, providing the ejection of secondary particles within a useful solid angle of 0.4 at the field of 0.46 T. For the target polarization reverse with the interval of 10 min a special mechanical support to rotate the magnet along the beam axis within ±180 deg has been foreseen. 3 refs.; 3 figs
