Ferrite Ring Magnet - 72mm (OD) x 32mm (ID) x 15mm (H)
Large, durable, and highly versatile, this Ferrite Ring Magnet measures 72mm outer diameter (OD) x 32mm inner diameter (ID) x 15mm height (H) and is manufactured from high-quality ferrite magnetic material. Designed for industrial, mechanical, electrical, and educational applications, this substantial ring magnet provides reliable magnetic performance while offering exceptional resistance to corrosion, oxidation, and environmental exposure.
Ferrite magnets are one of the most widely used permanent magnet materials due to their affordability, durability, and long-term magnetic stability. Unlike rare earth magnets, ferrite magnets do not require protective coatings, making them ideal for both indoor and outdoor applications where moisture, humidity, and harsh operating conditions may be present.
The large central bore and robust ring design make this magnet suitable for installation around shafts, rods, tubes, bearings, and mechanical components. Commonly used in motors, generators, loudspeakers, magnetic couplings, sensing equipment, industrial machinery, and custom magnetic assemblies, ferrite ring magnets remain a trusted choice across many industries.

Please Note
Ferrite magnets are hard and durable but can be brittle. Care should be taken during handling and installation to avoid chipping or cracking from impact. While ferrite magnets generally offer lower magnetic strength than neodymium magnets, they provide outstanding durability, environmental resistance, and cost-effectiveness. Keep away from children, sensitive electronic devices, and magnetic storage media. Holding performance will vary depending on the application and mounting arrangement.
Pull Force Information
Pull Force Information
Pull force refers to the maximum holding strength of a magnet. Measured in kilograms, it represents the amount of weight a magnet can support when attached to 10mm thick mild steel, with full, flat, and direct surface-to-surface contact.
A magnet's pull force can be affected by several factors, including its orientation (horizontal vs. vertical) and the presence of any air gaps between the magnet and the surface it’s attached to.
