Description
Product Overview
BY JMY presents a set of eight high‑performance ferrite block ceramic magnets designed for versatility across educational, hobbyist, and light‑industrial settings. Each magnet measures 1.9 × 0.9 × 0.4 inches (approximately 48 × 22 × 10 mm) and is fabricated from Grade 8 ferrite material, delivering an internal magnetic flux density of roughly 3,850 Gauss. This translates to a holding force of up to 29 lb (13 kg) per magnet when conditions are optimal. The magnets are coated with a protective layer that prevents rust and corrosion, ensuring reliable performance in both fresh‑water and salt‑water environments. The compact rectangular shape makes them easy to integrate into a wide range of projects, from suspended train models to magnetic tool holders in a garage workshop.

Usage
These magnets excel in educational demonstrations, allowing teachers to illustrate magnetic fields, force vectors, and material properties with tangible, hands‑on experiments. In hobbyist applications, they serve as the core component for DIY magnetic levitation projects, custom magnetic closures, and creative art installations. Their robust holding capacity also makes them suitable for light‑industrial tasks such as securing small metal parts on workbenches, creating temporary magnetic fixtures, or building prototype magnetic assemblies. Because the magnets are non‑ferrous and do not attract iron filings, they are safe for use around electronic components, making them a reliable choice for electronics hobbyists and makerspaces.
Why Choose Us
Choosing BY JMY means selecting a brand committed to quality, consistency, and customer satisfaction. Our ferrite magnets undergo rigorous testing to verify magnetic strength, dimensional accuracy, and corrosion resistance.

FAQ
What is the maximum holding force of each magnet?
Each magnet can hold up to approximately 29 lb (13 kg) under ideal conditions, which corresponds to a magnetic flux density of about 3,850 Gauss.
Are these magnets safe to use around electronic components?
Yes. Ferrite magnets do not produce strong stray fields that can damage most electronic components, making them suitable for hobby electronics and prototyping.
Can the magnets be used in marine or outdoor environments?
Absolutely. The protective coating prevents rust and corrosion, allowing the magnets to function reliably in both fresh‑water and salt‑water settings.
Do the magnets come with any mounting hardware?
No additional hardware is included; however, the flat surfaces and strong magnetic pull make them easy to attach directly to metal surfaces or embed in custom fixtures.
What is the return policy if I am not satisfied?
We offer a 30‑day money‑back guarantee. If the magnets do not meet your expectations, simply contact our support team for a hassle‑free return.
