Large Ceramic Donut Magnets Burnur 2.87″ OD Ring Dark Grey Pack of 2

Description

Product Overview

The Burnur Large Ceramic Donut Magnets are precision‑engineered ferrite ring magnets designed for demanding industrial and hobbyist applications. Each magnet measures 2.87 inches in outer diameter, 1.26 inches in inner diameter, and 0.4 inches in thickness, delivering a robust axial magnetic field that can securely hold metal components, tools, and small objects. Constructed from non‑brittle dark grey ceramic material, these magnets resist chipping and cracking even under repeated handling, making them a reliable choice for long‑term projects. The magnets are magnetized axially through the full thickness, ensuring uniform pull across the entire surface. Packaged in a compact 5.08 × 5 × 2.64‑inch box, the two‑piece set is lightweight at just over 10 ounces, yet powerful enough for scientific displays, mounting bases, and paper‑clip traps. Burnur, a reputable manufacturer in the industrial magnet market, guarantees consistent performance and dimensional accuracy, as reflected in the product’s positive 4.3‑star rating from 19 verified customers.

Usage

These donut magnets excel in a variety of environments, from classroom science labs to workshop benches and small‑scale manufacturing lines. In educational settings, teachers use them to demonstrate magnetic field lines, attract ferrous particles, and create interactive experiments that illustrate the principles of magnetism. DIY enthusiasts appreciate the magnets for building custom mounting solutions, such as attaching LED strips to metal surfaces, securing tool holders, or creating magnetic closures for cabinets. In industrial contexts, the magnets serve as reliable components for magnetic separators, conveyor belt pickups, and magnetic bases for measurement instruments. Their dark grey finish blends discreetly into most aesthetic designs, while the strong axial pull ensures that objects remain firmly attached even when subjected to vibration or movement. Whether you are constructing a prototype, assembling a display stand, or simply need a dependable paper‑clip trap, these magnets provide a versatile, low‑maintenance solution.

FAQ

What is the magnetic strength of these donut magnets?

The magnets are made from high‑grade ferrite, providing a strong axial pull suitable for holding small metal parts, tools, and accessories. Exact pull force varies with the size of the attached object, but they are rated for typical DIY and laboratory applications.

Can these magnets be used in humid or outdoor environments?

Yes. The ceramic ferrite material is highly resistant to corrosion and does not rust, making the magnets suitable for humid indoor settings and protected outdoor use.

Are the magnets safe to handle for children in educational settings?

While the magnets are non‑brittle, they are still strong and should be handled with care. Supervision is recommended for younger students, and magnets should be kept away from electronic devices and pacemakers.

Do the magnets come with any mounting hardware?

No additional hardware is included. The magnets are sold as plain rings, allowing you to integrate them with your own brackets, plates, or adhesive solutions as needed.

What is the warranty or return policy for these magnets?

Burnur offers a standard 30‑day return policy for defective or unsatisfactory items, along with technical support to help you integrate the magnets into your projects.
