Abstract
A magnetic erasing device including a magnet that includes an S pole and an N pole extending along an axial direction of the magnet, and a rotation mechanism for rotating the magnet in a housing around an axis of the magnet, wherein lines of magnetic force generated around the axis of the magnet during rotation of the magnet are designed to be applied to magnetic particles in the microcapsules to erase a visible image on a magnetic panel when the axis of the magnet is spaced from a surface of the magnetic panel by a predetermined distance.
