Abstract
A writing board (chalkboard) tool is designed according to the technical principle of attraction between iron materials and magnetic powder. The surface of the writing board (chalkboard) can attract writings of magnetic powder, so that characters in various colors and figures in various colors can be written on the writing board (chalkboard); in addition, a magnetic iron writing board (chalkboard) eraser (9) is covered with a cloth cover (10); when the cloth cover (10) is used with the magnetic iron writing board (chalkboard) eraser (9) to erase the writing board and after the magnetic powder on the writing board is attracted by the magnetic iron writing board (chalkboard) eraser, the cloth cover is placed in a magnetic powder collection box and is then taken off to allow the magnetic powder to leave the cloth cover; the use cycles so, so that saving and environment protection are achieved.
