A transport apparatus (3; 4) and a transport method for transporting carriers (31, 32; 310) in a machine (1) are provided. The transport apparatus (3; 4) comprises at least one carrier (31, 32; 310) for carrying a load, and a planar driving system for driving the at least one carrier (31, 32; 310) with magnetic force between at least two positions in a plane spanned by a first and second moving direction (x, y), wherein at least one carrier (31, 32; 310) of the at least one carriers (31, 32; 310) comprises less magnetic force exerting elements (312; 322) which are orientated in the second moving direction (y) for driving said carrier (31, 32; 310) in the first moving direction (x) than said carrier (31, 32; 310) comprises magnetic force exerting elements (311, 313; 321, 323) which are orientated in the first moving direction (x) for driving the carrier (31, 32; 310) in the second moving direction (y), so that the planar driving system and said carrier (31, 32; 310) interact to drive said carrier (31, 32; 310) in the first moving direction (x) in a smaller range than in the second moving direction (y).
