Uses for our rare earth disc magnets:

Circular Neodymium disc magnets are very powerful and because of their relatively small dimensions, can still operate effectively in cramped or confined spaces. This makes Neodymium disc magnets a common choice for customers who want to add a magnetic feature to their products or replace the more traditional attachment mechanisms such as screws, clips or clamps with a more practical and more modern option. This magnetic product also has the added feature of a self-adhesive surface on one side. The adhesive can be exposed by peeling away the backing and this allows the magnet to be attached to surfaces other than metallic ones. This means magnetic hold can be extended to almost any product or design including ones made of timber, plastic or ceramic materials.
The field of these strong Neodymium discs is often strong enough to pass through thin exterior material and form an invisible bond or even a magnetic closure between two surfaces. Whether a large-scale manufacturer or home-based hobbyist, strong disc-shaped magnets can transform an average product design or artistic work into something more practical, more user friendly or more contemporary in style.
