Description:

Neodymium (NdFeB) ring magnets are powerful rare-earth magnets with a circular shape and a central hole. They offer high magnetic strength and versatility and are commonly used in motors, sensors, loudspeakers, and various industrial applications.

Specifications:

• Material: Neodymium Iron Boron (NdFeB)
• Shape: Ring (Circular with a Center Hole)
• Tolerance: ±0.004″ for all dimensions
• Grade: N52 (one of the strongest commercially available grades)
• Plating/Coating: Nickel (Ni-Cu-Ni) or Epoxy (for corrosion resistance)
• Magnetization Direction: Axial or Diametrical
• Maximum Operating Temperature: ~80°C (for standard N-grade magnets)

Key Features:

• High Magnetic Strength – N52 grade provides a strong magnetic field in a compact size.
• Easy Mounting – The central hole allows secure attachment with screws, bolts, or rods.
• Corrosion Resistance – Coated with Nickel, Zinc, or Epoxy for durability and rust prevention.
• Wide Applications – Used in motors, electronics, medical devices, and industrial equipment.

Common Applications:

• Motors & Generators – Essential for high-performance electric motors and alternators.
• Electronics & Sensors – Used in magnetic sensors, speakers, and microphones.
• Industrial & Mechanical Uses – Magnetic couplings, holding systems, and filtration applications.
• DIY & Engineering Projects – Perfect for crafts, scientific experiments, and prototype designs.
