The present invention provides a method and apparatus for manufacturing a magnetic drawing board having a plurality of areas, each of which is designated with a specific color, with clear border between adjacent areas of different color. The present invention makes use of magnetic force to ensure that magnetic particles of a specific color will be filled into cells designated for that specific color. As a result, the present invention is capable of manufacturing a magnetic drawing board with a clear division of areas of different colors. There is no longer any limitation on the size and shape of the areas of different colors in the present invention.
