Abstract
A gradient magnetic field coil is excited by coil exciting means, thereby a gradient magnetic field being generated. The gradient magnetic field generates eddy current in an eddy current generating portion, the magnetic field due to this eddy current disturbing the gradient magnetic field. Means for compensating the magnetic field due to the eddy current is disposed, this means having a transmission function representing an inverse of the transmission function of a gradient magnetic field system including the gradient magnetic field coil and the eddy current generating portion.
