A magnetic bearing includes at least one inner bearing part; at least one outer bearing part which surrounds the inner bearing part; at least one permanent magnet and at least one flux guiding element which is positioned axially in relation to a rotation axis, adjacent to the permanent magnet(s), for guiding the magnetic flux of the permanent magnet(s) to one of the two bearing parts, and at least one superconductor on the other of the two bearing parts. The permanent magnet(s) and superconductor interact with each other in such a way that a bearing gap is formed around the rotation axis between the inner bearing part and the outer bearing part. The permanent magnet(s) is/are radially set back towards the bearing gap in relation to the flux guiding element(s) in a radial direction, perpendicular to the rotation axis. Each permanent magnet is held at least one of inwards and outwards by a corresponding radial holding element, at least on the side facing towards the bearing gap.
