A system and method control magnetic adhesion of a wheel to a surface using internal cancellation magnets. An inner annular disc of the wheel comprises a non-magnetic material and has first and second apertures which retain magnets while an outer annular disc comprises a ferromagnetic material and is disposed on a side of the inner annular disc and has a non-magnetic isolator ring which extends in a serpentine manner. In one configuration, the curves of the serpentine isolator ring isolate the first magnets from the second magnets. In another configuration, the outer annular disc rotates relative to the inner annular disc to dispose the curves of the serpentine isolator ring in a second position to allow magnetic interaction between the first and second magnets to generate a second magnetic flux between the second magnets and the ferromagnetic surface to thereby decrease the adhesion of the wheel to the ferromagnetic surface.
