A magnetic resonance apparatus has a gradient tube at which at least one gradient coil with current flowing therein in operation is arranged, and at which a number of elements for generating a force acting on the gradient tube as needed are arranged, with the positions of the elements being selected dependent at least on the vibratory mode of the gradient tube, so that a counteracting mode is excited given drive of the elements. The elements serving for the excitation of X and/or Y modes are distributed in the middle and around the circumference of the gradient tube with respect to the length of the gradient tube and/or the elements serving for the excitation of the Z mode are distributed along the length and the circumference of the gradient tube.
