These rubberised magnet systems with threaded stud work great on delicate surfaces. The rubber coating not only protects from scratches but also increases the weight capacity in shear direction and makes them slip-resistant.
Compared to standard pot magnets without a rubber coating, these rubberised magnet systems are thinner and more discreet. There is a steel plate under the rubber coating with 4 embedded magnets. They are arranged alternately with north and south pole facing up. As a result, you will be able to combine these magnet systems with each other. But please be careful, because once two of these magnet systems are fully joined, it will be very difficult to separate them again.
Please note that rubberised magnet systems will start to rust when permanently used outdoors. Our ferrite pot magnets, on the other hand, are rust-proof.
The full adhesive force is achieved when the ferromagnetic counterpart is smooth and of sufficient thickness and when the magnet system makes direct and full flush contact. Magnet systems start to lose much of their adhesive force at a small distance to the ferromagnetic surface. This characteristic is more pronounced in magnet systems than in other ferrite and neodymium magnets.
