Abstract
A moving device comprises at least a first element provided with main magnets and a second element provided with coils. The main magnets are arranged in a grid of rows and columns, wherein main magnets in adjacent rows are oppositely polarised and staggered relative to each other. The coils can be energized for moving the first element relative to the second element in a direction parallel to the rows as well as in a direction parallel to the columns. Auxiliary magnets of the same polarity are disposed between the main magnets at least in a number of rows, wherein the strength of the magnetic field of said auxiliary magnets is different from that of the main magnets.
