Description
Product Overview
Our Ferrite Donut Magnets are engineered with precision to meet the demanding needs of both hobbyists and professionals. Each magnet measures 50 mm in outer diameter, 25 mm in inner diameter, and 8 mm in thickness, providing a substantial magnetic field thanks to the Y35 grade ferrite material. The donut shape with a central hole makes them ideal for mounting on shafts, rods, and other components where a through‑hole is required. Constructed from C8 grade ceramic, these magnets exhibit high resistance to demagnetization, corrosion, and oxidation, ensuring long‑term performance even in harsh environments. The pack includes six identical pieces, allowing for flexible configurations in projects ranging from simple classroom demonstrations to complex industrial assemblies.

Usage
These versatile magnets find application across a broad spectrum of settings. In educational labs, they serve as reliable tools for teaching magnetic principles, enabling students to explore attraction, repulsion, and magnetic flux without safety concerns. DIY enthusiasts appreciate the strong holding power for craft projects, such as magnetic jewelry, custom tool holders, and artistic installations. In industrial contexts, the magnets are employed in motor and generator prototypes, sensor housings, speaker assemblies, and magnetic couplings where a secure yet removable connection is essential. Their compact size and robust magnetic force also make them suitable for scientific experiments, magnetic levitation demonstrations, and prototype development for new products.

FAQ
What is the magnetic strength of these donut magnets?
The magnets are rated at Y35, which provides a strong magnetic field that surpasses standard ceramic ring magnets, making them suitable for both light and medium‑load applications.
Are the magnets safe to handle?
While the magnets are robust, they are brittle and can chip if struck together. It is recommended to separate them gently using a non‑magnetic tool to avoid breakage.
Can these magnets be used in high‑temperature environments?
Ferrite magnets maintain their performance up to approximately 250 °C (482 °F). For applications exceeding this temperature, alternative magnet types should be considered.
Do the magnets have any coating?
These magnets are uncoated C8 grade ceramic, offering natural resistance to corrosion and oxidation. If additional protection is required, a separate coating can be applied.
What is the recommended storage method?
Store the magnets in a dry, non‑magnetic container away from strong magnetic fields to preserve their strength and prevent accidental attraction that could cause damage.
