<p>According to the present invention, a magnet pixel board has a plurality of magnet pixel elements wherein magnet pixel elements comprise a cell area on a cubic space, a transparent protecting film on the front surface and a rear surface processing part on the rear surface to include magnet elements. The magnet element in the magnet pixel elements has a north pole and a south pole wherein the north pole is coated with a bright color and the south pole is coated with a dark color or the south pole is coated with a bright color and the north pole is coated with a dark color, thereby distinguishing light and shade according to the recorded content with use of natural light. A method for recording content on the magnet element in the magnet pixel elements uses a magnet pen element or an electromagnet controlling signal on the rear processing part.</p> |
