A magnetic resonance diagnosing apparatus has a static magnetic field magnet, a gradient magnetic field coil, a transmitter/receiver probe, a Fourier transformer, a discriminator, a DC offset changer, and a controller. The Fourier transformer transforms a time-region magnetic resonance signal acquired by the transmitter/receiver probe to a frequency-region signal in accordance with Fourier transformation. The discriminator discriminates whether the line width of the frequency-region magnetic resonance signal is not more than a predetermined value. Based on the line width of the frequency-region magnetic resonance signal, the direct current offset changer adjusts the current to be supplied at least to the gradient magnetic field coil so as to correct the offset of the static magnetic field.
