At Neomag Inc., we supply high-performance Neodymium Ring Magnets engineered for industrial, electronic, and precision applications.
All standard products available online are axially magnetized, providing strong and concentrated magnetic force for most applications. Custom magnetization options are also available upon request for specialized engineering needs.
Ring magnets are circular magnets with a center hole, similar in shape to a washer or donut. They are typically measured by outer diameter (OD), inner diameter (ID), and thickness.
The center hole allows ring magnets to be easily mounted onto shafts, rods, screws, or mechanical components, making them ideal for both industrial and electronic applications.
At Neomag Inc., our Ring Series includes standard ring magnets, countersunk ring magnets, and precision-engineered custom ring magnets for a wide range of applications.
• Axial Magnetization (Standard)
Magnetic poles are located on the flat circular faces (top and bottom), providing strong direct holding force and concentrated magnetic performance.
• Diametrical Magnetization (Custom Only)
Magnetic poles are positioned on opposite sides of the curved outer surface, commonly used in rotating systems, sensors, and specialized engineering applications.
• Multi-Pole Magnetization (Custom Only)
Multiple alternating north and south poles around the ring are available for motors, encoders, and advanced magnetic systems.
Ultra-Strong Magnetic Force
Neodymium (NdFeB) magnets are the strongest commercially available permanent magnets, offering superior magnetic performance in compact sizes.
Convenient Center Hole Design
The center hole allows for:
• Easy mounting and installation
• Integration with shafts and fasteners
• Stable positioning in rotating systems
Wide Range of Sizes
We offer a comprehensive selection of:
• Outer diameters (OD)
• Inner diameters (ID)
• Thicknesses
Suitable for both miniature electronic components and heavy-duty industrial applications.
