A magnetic roller 100 for being rotatable on a ferromagnetic surface is provided. The magnetic roller 100 includes a roller wheel 110 having an inner space 112, a magnetic array arrangement 120 and at least one first drive mechanism 130. Further, the magnetic array arrangement 120 is adapted to be swivelably disposed within the inner space 112 of the roller wheel 110. The magnetic array arrangement 120 includes a strong adhesion force side 122 and a weak adhesion force side 124. Furthermore, the first drive mechanism 130 is configured to swivelably drive the magnetic array arrangement 120. The first drive mechanism 130 swivelably drive the magnetic array arrangement 120 to direct the strong adhesion force side 122 towards the oncoming ferromagnetic surface, and, to direct the weak adhesion force side 124 towards the foregoing ferromagnetic surface to enable the roller wheel 110 to move forward on the ferromagnetic surface. |
