  In thin steel plate production lines, contact conveyance by rollers is used, so scratches on the surface of the plates and plating defects are problems. Therefore, non-contact magnetic levitation conveyance of thin steel plates using the attractive force of electromagnets has been proposed. We studied a magnetic levitation system for thin steel plates that uses both electromagnets and permanent magnets. While a thin steel plate was magnetically levitated, we investigated the effect of changing the position where tension is applied by a magnetic field from the horizontal direction on the placement of permanent magnets optimized by a genetic algorithm. From the result, we found that this change had a positive effect on levitation performance.
