Abstract
A magnetic ring fixed removably onto a pencil/eraser, with a smaller internal diameter being between 1.5 mm and 3 cm. There is a cylindrical inner face centered on a longitudinal axis and an outer face opposite the inner face. There is a magnetic material distributed in a magnetic layer around the longitudinal axis with the direction of the overall magnetic moment of the magnetic ring parallel to the longitudinal axis. There is an elastic material, distinct from the magnetic material, that is elastically deformable between a rest position corresponding to a first value of the internal diameter of the ring, and a deformed position corresponding to a second value of the internal diameter of the ring. The difference between the first and second values being greater than or equal to 1 mm and the elastic material exhibiting a Young's modulus at 25° C. less than or equal to 1 GPa.
