We report the suppression of the Hall e ect in a mesoscopic Hall cross with a strong magnetic ÿeld only in the centre and vanishingly small outside. The local magnetic ÿeld is produced by placing Dy pillar on top of a structure with a high-mobility two-dimensional electron gas. The e ect is found to
