Neodymium disc magnets are incredibly versatile and have superb strength for their size. They’re used in many commercial applications including modular retail displays and point of sale stands for holding panels to a steel framework and many new packaging designs use them cleverly trapped behind layers of cardboard to provide invisible closing mechanisms.
They are equally useful around the home for DIY and home improvement. Knife racks, shutters and blinds can all be improved with magnets. You can even use them to find timber joists in a studded plasterboard wall!
Circular disc magnets can be fixed in place using adhesive or can be pushed into drilled holes in wood or plastic.
