RING Magnets
High-Performance Circular Solutions
Specialized Geometry for Complex Assemblies. Neodymium ring magnets (also known as donut magnets) are essential for applications requiring a central clearance for shafts, bolts, or sensors. As a core part of our extensive Neodymium Magnets catalog, these rare earth rings offer the same extreme N52 strength as our blocks and discs but with a hollow center designed for mechanical integration.
Common Uses for Ring Magnets:
- Electric Motors & Rotors: Ideal for mounting directly onto rotating shafts.
- Speaker Assemblies: Used to create focused magnetic fields in audio equipment.
- Magnetic Couplings: Perfect for torque transfer without physical contact.
Understanding Ring Magnet Magnetization
Unlike standard discs, neodymium ring magnets can be magnetized in different directions depending on your project needs. Choosing the right orientation is vital for performance:
- Axially Magnetized: The North and South poles are on the flat circular faces. This is the most common type, used for stacking or attaching to flat steel surfaces.
- Diametrically Magnetized: The poles are on the curved sides (left and right). These are specifically used in rotary sensors and motors where the magnetic field must flip as the magnet spins.
Mounting and Stability
One of the biggest advantages of a ring magnet is the ability to secure it mechanically. While adhesives work well for Small Ring Magnets, larger industrial rings can be bolted down or held in place by a central pin. This prevents the "sliding" effect often seen with standard blocks under high-vibration conditions.
Durability & Coating
To ensure long-term performance, all our rings feature a Ni-Cu-Ni triple-layer coating. This protects the brittle NdFeB material from oxidation. If you are using these in high-moisture environments, such as marine sensors, we recommend checking our Coated Neodymium Magnets section for epoxy or plastic-shielded options.
Recommended Ring Magnets for Performance
The Neodymium Ring Magnets N52 represent our highest-strength circular magnets. These are the preferred choice for industrial engineers who need maximum flux density in a compact, hollow profile.
For precision tasks, the Small Rare Earth Ring Magnets provide a versatile solution. These are commonly used in jewelry clasps or scientific instruments where a lightweight, circular magnetic field is required.
