Rubber Coated Magnet

Rubber coated magnets, alternatively known as rubber covered magnets, encompass a magnetic circuit that is encased within a protective layer of rubber material. This layer shields the magnet from environmental damage and prevents it from scratching surfaces it comes in contact with. Rubber coated magnet is high in magnetic strength and weatherproof, so they are ideal for indoor and outdoor applications where robust pull force is necessary, but surface protection is also critical.

The basic structure of rubber coated magnet comprises a ferromagnetic steel plate, Neodymium magnets, and protective rubber casing. Functionally similar to pot magnets as magnetic holding assemblies, rubber coated magnets stand out by offering enhanced surface protection, improved corrosion and impact resistance, and greater friction, benefits that are a direct result of their rubber casing. However, the presence of this rubber casing leads to a distinct magnetic circuit within the rubber coated magnets, different from that in pot magnets. The magnetic circuit inside the rubber casing is constructed with neodymium magnets and a ferromagnetic steel plate. Typically, the neodymium magnets, which are often disc-shaped, are affixed to the steel plate in an alternating pole arrangement. The pull force of rubber covered magnets can be adjusted through the optimization of the magnetic circuit. In conjunction with this, the rubber material undergoes tailored modifications, ensuring a collaborative and precise tuning that enables the magnets to fulfill a diverse array of specific usage requirements.
