1. An arrangement for measuring at least one of a force or a moment on a machine extending along an axis, in which the machine element includes a magnetization area for a magnetization extending circumferentially around the axis, the arrangement further comprises at least one first magnetic field sensor and one second magnetic field sensor each of which are formed for individually measuring a first and a second directional component of a magnetic field caused by the magnetization and by the at least one of the force or the moment, wherein the first directional component of the magnetic field measurable with the first magnetic field sensor and the second directional component of the magnetic field measurable with the first magnetic field sensor have different orientations, wherein the first directional component of the magnetic field measurable with the second magnetic field sensor and the second directional component of the magnetic field measurable with the second magnetic field sensor have different orientations, and the first magnetic field sensor and the second magnetic field sensor are arranged at different circumferential positions about the axis.
