An arrangement of cancellation electromagnets control magnetic adhesion of a wheel to a surface. The wheel has an inner annular disc composed of a non-magnetic material with apertures which retain electromagnets and permanent magnets, and an outer annular disc composed of a ferromagnetic material which is disposed on a side of the inner annular disc, with a non-magnetic isolator ring having curves extending in a serpentine manner. In one embodiment, the curves isolate the electromagnets from the permanent magnets. In another embodiment, the outer annular disc is rotated 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 electromagnets and the permanent magnets to generate a second magnetic flux between the permanent magnets and the ferromagnetic surface which decreases adhesion of the wheel to the ferromagnetic surface. A method implements the system.
