A magnetic resonance diagnostic apparatus sequentially generates a high-frequency magnetic field and a gradient magnetic field to generate a MR signal from a subject in a imaging space and reconstructs a MR image of the subject on the basis of the MR signal. As a result, a stimulative magnetic field that stimulates part of the subject develops so as to cross the gradient magnetic field. The stimulative magnetic field occurs in synchronization with the gradient magnetic field. A canceling magnetic field that opposes the stimulative magnetic field is generated. The canceling magnetic field has the reversed polarity to that of the stimulative magnetic field. As a result, the resultant magnetic field of the stimulative magnetic field and canceling magnetic field has a lower intensity than that of the stimulative magnetic field, so that the stimulus the subject feels becomes smaller.
