Abstract
The front erase magnetic drawing board (20) comprises of magnetic drawing panel (21), magnetic pen (40) and magnetic eraser (30). It allows using magnetic pen (40) and erasing from the front using the magnetic eraser (30). The magnetic eraser (30) has a front magnet (31 ) in front of the magnetic drawing panel (21 ) and a back magnet (35) beneath the magnetic drawing panel (21 ). The front magnet (31 ) can be moved around from the front of the drawing board (20). The back magnet (35) will follow the front magnet (31 ) due to the magnetic attraction between them and erase the drawing in its path. The magnetic drawing board (20) can have long spans with the incorporation of stiffeners (22). The front erase magnetic drawing board (20) can be further adapted by including an electromagnet layer and front drawing magnet, and sensor layer to allow it to display saved images or to save drawn images.
