Safety Warning: All magnets are fragile the same way a dish plate of the same thickness would be. These magnets especially the thinner ones should be treated the same way you would a thin dinner plate. Should one of these magnets break the edges are extremely sharp (like broken glass). Safety Warning: These neodymium magnets are not for children. They may break and cut severely. Children that may place things in their mouths should be kept away from these magnets. If taken into the mouth these neodymium magnets may pinch across internal organ membranes with deadly results.
About Neodymium Magnets
Neodymium rare earth Ring magnets are actually 10x stronger than the strongest ceramic magnets! Unlike most other types of magnets, Neodymium is highly resistant to demagnetization and will not lose their magnetization around other magnets or if dropped. They are magnetized through the thickness. They are composed of neodymium iron boron magnetic material. About Rare Earth Neodymium Magnets Rare earth magnets are the strongest type of permanent magnet currently made. All Neodymium magnets are rare earth magnets but there are other types of magnets in the rare earth family. Neodymium is however the most popular & cost effective. Rare earth magnets are the strongest type of permanent magnet currently made. The Rare earth family of magnets consist of basically 2 types of magnets. Neodymium magnets are notoriously resistant to demagnetization in and operating environment below 176 degrees F.. Neodymium is a rare earth element. Samarium cobalt magnets although not quite as strong, are a great substitute for neodymium when temperatures in the operating area reach more that 175 Degrees F. Neodymium, as sold on the market is actually an alloy consisting of the rare earth element neodymium, iron & Boron. The ratios of the mix are in part responsible for the strength differences of the magnets. You may see the element’s symbols Neodymium (Nd), Iron (Fe) & Boron (b). This rare earth Ring magnet was created through a sintering process. Sintering is the process of compacting and forming a mass of material (this case a alloy) with heat or pressure but keeping it from getting to the liquefaction stage then pressing it into the final magnet shape.
- Question: We have a large dresser drawer that keeps sliding open. Will these magnets work if attached to cabinet and dresser to keep drawer closed? Answer: You might need a couple in a couple different spots but yes I would think so Bruce Clements· June 26, 2021
- Would these magnets hold curtains together in an outside pergola? A: Yes if little wind. If you live in a windy area probably step up to an N52 1.26 x 1/4 Dave Curtis · November 23, 2017
- What about hanging tools? A: Hand tools are fine maybe 3/4 disc w/ countersunk hole at n52 just to be safe. Bobby · July 7, 2019
- Hanging knives? I would use an N45 or better 3/4" Disc just to make sure. Blue Moon · June 12, 2019
- Will these magnets hold a medium weight synthetic blanket down across the front of a car without damaging the finish of the car? I would think they would as they are pretty strong They have a very smooth finish so shouldn't cut through the blanket and mar the finish. By D. Jem
All magnets may chip and shatter, but if used correctly, can last a lifetime.
Keep away from pacemakers.
Not for children, parental supervision required.
COMMERCIAL USE ONLY.
If damaged please dispose of completely. Shards are still magnetized and if swallowed can inflict serious damage if magnets join inside the digestive tract.
Other DetailsThis product is covered by 10 year warranty on the magnetic strength under normal usage. Used in the environment which has high temperature and virbation will void this warranty. The product should not be used in the outdoor or high humid or salty environment except extra insulation measurement is taken.
