Ceramic Ring Magnets Master Magnetics 1.75″ OD 0.865″ ID Pack of 2

Description

Product Overview

Master Magnetics brings you a pair of high‑quality ceramic ring magnets engineered from ferrite material that offers exceptional resistance to both corrosion and demagnetization. The dimensions—1.75″ outer diameter, 0.865″ inner diameter, and 0.225″ thickness—provide a compact footprint while still delivering a respectable 2.17 lb pull force. These magnets are cast using a precise sintering process that ensures uniform magnetic density across the entire ring, resulting in reliable performance whether they are used in a laboratory setting or a rugged industrial environment.

Each magnet weighs approximately 2.4 ounces, making them light enough for easy handling yet substantial enough to maintain a stable magnetic field. The ceramic composition is inherently non‑magnetic to surrounding metal tools, which reduces the risk of accidental attraction to unintended ferrous objects during installation or transport. Additionally, the magnets are rated for operation at temperatures up to 400°F (204°C), allowing them to function reliably in applications that involve heat exposure, such as motor housings, furnace doors, or high‑temperature testing rigs.

Beyond the core specifications, the product includes a convenient pack of two magnets, giving users the flexibility to experiment with magnetic configurations, create modular assemblies, or simply keep a spare on hand. The magnets are supplied without any adhesive, enabling users to choose the most appropriate bonding method—whether that be epoxy, silicone, or mechanical fastening—based on the specific demands of their project.

Manufactured by Magnet Source, a trusted name in the magnetic industry, these ring magnets have earned a solid reputation reflected in a 4.5‑star rating from over a thousand verified customers. Their popularity in the Amazon Best Sellers Rank (#11 in Industrial Ceramic Magnets) underscores their broad appeal across hobbyists, educators, and professional engineers alike.

Usage

These ceramic ring magnets excel in a wide range of DIY and professional scenarios. For hobbyists, they can be glued to the back of wooden or plastic prototypes to create magnetic hinges, detachable panels, or custom tool holders. In educational settings, the magnets serve as hands‑on teaching aids for physics experiments that demonstrate magnetic fields, torque, and the effects of temperature on magnetism.

Industrial users often employ the magnets in material handling systems where a non‑permanent magnetic hold is required. Their ability to withstand high temperatures makes them suitable for integration into conveyor belts that transport heated metal parts, as well as for securing components in automotive engine bays where heat is a constant factor. The compact ring shape also allows for easy insertion into drilled holes or slots, providing a discreet yet powerful magnetic anchor point.

Because the magnets are corrosion‑resistant, they can be used outdoors for applications such as magnetic signage, garden tool organization, or even in marine environments where exposure to moisture is inevitable. The 2.17 lb pull force is sufficient to hold medium‑weight objects without the risk of sudden disengagement, offering a reliable solution for both temporary and semi‑permanent installations.

FAQ

What is the maximum temperature these magnets can withstand?

The magnets are rated for continuous operation up to 400°F (204°C) without loss of magnetic strength.

Can I use these magnets for holding heavy tools?

With a pull force of 2.17 lb per magnet, they are ideal for medium‑weight items such as tool handles, small metal plates, or educational experiment components. For heavier loads, consider using multiple magnets or a different magnet class.

Do the magnets come with adhesive?

No adhesive is included. This allows you to select the bonding method that best fits your application, whether it be epoxy, silicone, or mechanical fastening.

Are these magnets safe for use around electronic devices?

Ceramic ferrite magnets have a relatively low magnetic field compared to neodymium magnets, making them generally safe around most electronic equipment. However, keep them at a reasonable distance from sensitive components to avoid interference.

What is the warranty period for these magnets?

Master Magnetics offers a one‑year limited warranty covering manufacturing defects. Contact our support team for warranty claims or replacement requests.
