Connecting magnets, also known as joining magnets, are specialized magnetic components designed to create secure, temporary bonds between two or more objects. They typically feature strong magnetic materials like neodymium (NdFeB), ferrite, or samarium cobalt, ensuring high magnetic force for reliable connections. Unlike regular magnets, connecting magnets often have optimized shapes—such as discs, blocks, or rings—with flat or precision-machined surfaces to maximize contact area, enhancing bonding strength.

Their core function lies in enabling tool-free assembly and disassembly, making them ideal for applications where permanent fastening (like screws or glue) is impractical. For example, in furniture assembly, connecting magnets can join detachable shelf brackets to frames, allowing easy reconfiguration. In electronics, they secure battery covers or detachable panels, simplifying maintenance. They also find use in educational models, where students can build and modify structures without damaging parts.

Key advantages include adjustable positioning and damage-free use—they leave no holes or residue on surfaces. However, users must consider weight capacity (neodymium connecting magnets can hold 5–20 kg depending on size) and surface compatibility (works best on ferrous metals; non-ferrous surfaces may require magnetic plates). Additionally, choosing the right magnet grade (e.g., N52 for maximum strength) ensures the connection meets specific load needs, making connecting magnets a versatile solution for both industrial and household tasks.
