Adhesive-backed circular magnets are a practical magnetic material widely used in daily life, industry, electronics, and other fields. They are favored by users for their ease of installation. Based on differences in material and performance, there are two main types of adhesive-backed circular magnets: adhesive-backed flexible rubber circular magnets and adhesive-backed rare earth neodymium circular magnets. The following is an introduction to these materials.
Flexible rubber circular magnets with adhesive backing
Rubber circular magnets with adhesive backing, also known as rubber soft magnets, are made primarily from ferrite magnetic powder or neodymium iron boron magnetic powder mixed with rubber material, then processed through calendering or injection molding. The adhesive backing on their surface is typically 3M adhesive or domestically produced high-adhesion double-sided tape, making them easy to apply directly. Some customers may specify the brand and type of adhesive backing.

The accompanying image shows a flexible rubber ferrite circular magnet with adhesive backing.
Features:
Highly flexible, bendable, and cuttable, suitable for irregular or curved surfaces.
Generally multi-pole magnetized with weak magnetic force, suitable for non-structural adsorption scenarios.
Relatively low cost, suitable for bulk use.
Smooth circular edges, unlikely to scratch objects or human skin.
Mainly used for refrigerator magnets, whiteboard magnets, advertising signs, children's puzzle toys, home decoration magnetic hangers, display board fasteners, etc.
Neodymium circular magnets with adhesive backing
Made of sintered neodymium iron boron, these magnets have a smooth surface that is ideal for attaching high-performance industrial-grade double-sided adhesive tape. They are suitable for use on a variety of surfaces, including metal, plastic, and glass.

Neodymium iron boron circular magnets with adhesive backing. Simply peel off the adhesive backing to use.
The characteristic of this type of adhesive-backed magnet is its powerful magnetism, which is many times stronger than the type described above. Similarly, it is also significantly more expensive. Common sizes include 10x1mm, 10x2mm, 12x2mm, 15x1mm, and 20x2mm.
In terms of application, it is suitable for fixing posters, photos, paintings, notices to whiteboards, and metal file cabinets. It can be used to make magnetic closure boxes and cabinet doors. It can also be used for smart speakers, mobile phones, tablets, sensors, and magnetic shells for digital devices. Other applications include gift boxes, packaging magnetic clasps, and display board structures.
When it comes to selection, users should choose based on specific application scenarios, magnetic requirements, budget costs, and appearance.
