Shape memory alloys are programmed to memorize original trained shape. Ni Mn Ga is one of the ferromagnetic shape memory alloys. It is used as actuator, and sensor due to large output strain at high frequencies. This work presents a study on enhancing magnetic properties of thermally treated alloy by using new method of training. Single near stoichiometric composition was produced. Elemental analysis showed homogeneity of the alloy. XRD pattern revealed Martensitic phase peaks. Transformation temperature was found to be below 100 CO. Training was applied by hydrostatic pressing die. Different training pressures were obtained using hydraulic press. After applying hydrostatic pressures stating from 2.5 bar to 10 bar, it was found that pressures up to 7.5 bar will the coercivity and saturation magnetization of the alloy, while loads beyond 7.5 bar lessened these magnetic properties
