A pulley (15) for cooperating with a suspension traction member (7) in an elevator (1) is proposed. Therein, the pulley (15) comprises a magnetic field generator (35) for generating a magnetic field such as to induce attractive forces upon a magnetisable portion of the suspension traction member (7) in a direction (27) orthogonal and/or towards a middle line (29) along a circumferential surface (21) of the pulley (15). Due to the forces induced by the generated magnetic field, the suspension traction member (7), typically including cords comprising a magnetisable material such as steel, is attracted towards the circumferential surface (21) of the pulley (15), particularly towards the middle line (29) such as to be centred and aligned with the circumferential surface (21) of the pulley (15). Furthermore, in case the circumferential surface (21) of the pulley (15) and a traction surface of the suspension traction member (7) are profiled with complementary profiles, the induced magnetic forces avoid any detachment of the suspension traction member (7) from the pulley (15), and therefore avoid any disengagement of the profiles, even in cases of temporarily slacking of the suspension traction member (7). Accordingly, any jumping or even jumping-off of the suspension traction member (7) may be avoided.
