A magnetic drawing apparatus including image forming means, image erasing means, motion generating means, movement control means, visible motion indication means and a main housing, wherein:
- said image forming means include a plurality of magnetic cells which collectively define an image forming surface, said magnetic cells containing a viscous fluid and magnetic powder;
- said image erasing means include a magnetic image eraser which is adjacent to said image forming means, said magnetic image eraser being connected to said motion generating means and movable relative to said image forming means to erase an image on said image forming means;
- said motion indication means is movable in synchronization with said magnetic image eraser;
- and
- said movement control means include means for actuating and controlling said motion generating means to erase an image.
A toy drawing board including image forming means, image erasing means, motion generating means, motion indication means, sound generation means, movement control means and a main housing, wherein:
- said image forming means include a plurality of magnetic cells which collectively define an image forming surface, said magnetic cells containing viscous fluid and magnetic powder;
- said image erasing means include a magnetic image eraser which is adjacent to said image forming means, said magnetic image eraser being connected to said motion generating means and movable relative to said image forming means;
- said motion indication means includes a visible indicia which is indicative, representative or characteristic of an object, the audible sound generated by said sound generating means being indicative, representative or characteristic of said object;
- said sound generation means generates audible sound during the movement of said magnetic image eraser;
- and
- said movement control means include means for actuating said motion generating means and means for selecting the direction of movement of said magnetic image eraser with respect to said image forming means.
