A magnetic suspension system (MC1; MC2; MC3) for a vehicle (20) is described comprising: a rail (30) made of material reactive to a magnetic field and comprising two opposite side surfaces (R1, R2); a skid (50) which slides on the rail and, being substantially U-shaped, comprises two parallel arms (54) whose facing surfaces (P1, P2) delimit an empty space (G) partially occupied by the rail, each of the two opposed side surfaces of the rail, respectively facing one of the surfaces facing the two parallel arms, said skid being able to generate a magnetic field with a polar axis (Q) orthogonal to those facing surfaces.
