The present invention provides a magnetic roller (100) to be rotated on a ferromagnetic surface. The magnetic roller (100) comprises: a roller wheel (110) having an inner space (112), a magnetic array facility (120) and at least one first driving mechanism (130). Moreover, the magnetic array facility (120) is adapted to be arranged to be turned in the inner space (1120) of the roller wheel (110). The magnetic array facility (120) includes a strong bonding strength side part (122) and a weak bonding strength side part (124). In addition, the first driving mechanism (130) drives the magnetic array facility (120) to be turned. The first driving mechanism (130) drives the magnetic array facility (120) to induce the strong bonding strength side part (122) toward an approaching ferromagnetic surface and induce the weak bonding strength side part (124) toward a previous ferromagnetic surface, thereby allowing the roller wheel (110) to be moved frontward on the ferromagnetic surface. The magnetic roller easily operates a magnetic bonding force to be easily moved on a ferromagnetic surface in a predetermined direction. |
