What Are N52 Neodymium Magnets?
N52 neodymium magnets are the strongest grade of rare-earth magnets commercially available, offering unmatched magnetic performance for demanding applications. As part of the NdFeB (neodymium-iron-boron) family, N52 magnets boast the highest maximum energy product (BH<sub>max</sub>)—up to 52 MGOe (Mega-Gauss Oersteds)—delivering exceptional holding strength in compact sizes.
Properties of N52 Neodymium Magnets
- Maximum Energy Product (BH<sub>max</sub>): 50-52 MGOe – The highest among neodymium magnets, delivering superior magnetic strength in compact sizes.
Coercivity (H<sub>ci</sub>): ~12,000 Oe – Provides excellent resistance to demagnetization.
Remanence (B<sub>r</sub>): ~14,800 Gauss – Ensures a strong and stable magnetic field.
Operating Temperature: Up to 80°C (176°F) – Higher than lower-grade neodymium magnets, but still requiring caution in extreme heat.
Corrosion Resistance: Typically coated with nickel, zinc, or epoxy to prevent oxidation and extend lifespan.
Brittleness: Like all neodymium magnets, N52 is sintered and can chip or crack if mishandled.

Diiferent Shapes of N52 Neodymium Magnets
From compact discs to powerful blocks, N52 neodymium magnets can be manufactured in various shapes and sizes, each altering the magnetic field for different applications. Below are N52 neodymium magnets popular forms:

- Ring Magnets: Ring magnets are doughnut-shaped magnets with a hole in the center, creating a circular magnetic field. They are commonly used in applications like speakers, sensors, motors, and magnetic couplings, where the central opening allows for the passage of shafts, wires, or other components while maintaining strong magnetic performance. The design helps focus the magnetic flux along the ring’s axis, making them useful in both industrial and electronic devices.
- Disc/Cylinder Magnets: Disc/cylinder magnets are flat, circular magnets with a uniform thickness, resembling a coin or a short cylinder. They generate a strong axial magnetic field (from one flat face to the other) and are widely used in motors, sensors, holding devices, and DIY projects due to their compact shape and high magnetic strength.
- Block/Rectangle Magnets: Block/rectangle magnets are cuboid-shaped magnets with flat, parallel surfaces that produce a strong and uniform magnetic field. They are commonly used in holding, lifting, magnetic assemblies, and industrial applications where a flat contact surface and high magnetic strength are needed. The special shape allows for efficient stacking and precise placement in devices like magnetic separators, closures, and robotics.
- Arc/Segment Magnets: Arc/segment magnets are curved magnets shaped like slices of a circle, designed to fit into rotating systems such as motors and generators. They provide focused directional magnetic fields, making them ideal for applications requiring smooth torque and efficient magnetic coupling in devices like electric motors, pumps, and wind turbines.
- Sphere Magnets: Sphere magnets are round, ball-shaped magnets that generate an omnidirectional magnetic field, making them useful for applications requiring free rotation or multi-axis movement, such as magnetic joints, sensors, and educational demonstrations.
