A magnetic eraser can be used for erasing markings drawn on a magnetic sheet. The magnetic eraser includes a housing with a magnet placed in the housing. The magnetic eraser also includes a first magnetic body placed between a first surface of the housing and the magnet. The first surface of the housing can provide a first erasing surface.

A modular assembly that is configured to be magnetically coupled to another object, such as a white board or glass board, is provided. The magnetic strength of the modular assembly can be adjusted. The modular assembly includes an article, such as a tray or other type of holder for receiving materials like markers and papers, and a module that houses magnets. The article can include a magnet housing portion with a magnet housing retention feature. The module can include a magnet housing with one or more magnets held therein. The magnet housing can include an article coupling feature. The module can slide into the magnet housing portion of the article and be secured in place by the engagement of the magnet housing retention feature and the article coupling feature.

A single sweep eraser system allows cleaning of a whiteboard with a single, simple and rapid motion across the board. The system provides track brackets and glides that support a cleaning bar applying sufficient pressure to a cleaning pad extending the height of the board to provide broad area cleaning without the need for the user to “lean in” hard against the cleaning pad. The tracks conveniently hold the cleaning bar off to one side of the board for ready access.
