Featuring a corrosion-resistant Ni-Cu-Ni triple-layer coating and manufactured under strict ISO 9001 standards, this magnet is perfect for professional DIY, educational science projects, and industrial applications requiring precision and lasting strength. ## Description This versatile powerful ring neodymium magnets is perfect for integrating into your projects or ideas. Under ideal conditions, it has a pull force of 38.5 lbs, and a gauss rating of 13,500 gauss. The magnetic strength will last forever under normal use. The dimensions of this magnet are 1-1/2" in diameter and 3/8" in thickness with a 1.065" hole going through the center of the magnet. Applications include: Magnetic holding, positioning, home improvement, kids’ science education and projects. And they are also great for DIY projects and many more. Please note: 1. All magnets are fragile and may chip or shatter, but if used properly under normal circumstances, they can serve you for a lifetime. 2. As with all magnets, keep away from pacemakers and sensitive electronics. Keep away from children under 5 years old. 3. The magnet pull force is tested in a standard settings, it has to be direct touch and direct pull from a 20 mm thick low carbon steel. This is industrial standard so magnets from different sources are comparable. Most home testing cannot meet this requirement and the testing result is less. ## Features - Powerful Permanent Magnets: Incredible Holding Power for its Size, Grade N45 - 38.5 lb Per Magnet Under Ideal Conditions, 13,500 Internal Gauss - Numerous Applications: Useful Magnets for Holding, Home Improvement, DIY Projects and Much More - Best Coating Available: Ni Cu Ni Triple Layer Coated.

One, it's too big and two, it's strong enough to at least cut you, if not break your finger. **Q: How do you know which direction north is?** A: hang it with a string. the side facing north direction is north pole. and side facing south direction is south pole. **Q: what is the inside diameter?** A: One and one sixteenth inches **Q: Will this magnet detect magnetic rocks?** A: magnets attract materials that are iron based, if there is a rock with a magnetic flux they will attract each other. If you drag a magnet on soil you will find that it will attract the iron based materials (mostly in a powder form). I'm not really sure what you are asking, I hope this information is helpful. ## Frequently Bought Together - CMS Magnetics® Super Strong Neodymium Magnets Ring N45 1-1/2"OD x 1.065" ID x 3/8" - Rare Earth Ring Magnet - Science Projects School and Magnetism Education - Realth Neodymium Ring Magnets Dia. 0.75''×0.12'' - 0.31'' Hole, Disc Magnets with Hole, Magnet Rings for Research Industrial Purposes Educational, 10 Pack(MT1910) - Magerial N42H NdFeB Arc Segment OR18xIR14x45deg.x20mm Strong Motor Magnets for Generators Wind Turbine Rotor Neodymium Permanent Magnet 36mm Diameter 20mm Height 8 Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/41909634-cms-magnetics-super-strong-neodymium-magnets-ring-n45-1-1](https://www.desertcart.com.ar/products/41909634-cms-magnetics-super-strong-neodymium-magnets-ring-n45-1-1) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-20*
