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: The description of this item, in a couple places it says 80 pieces, in another place it says 100 pieces. Which is it?
Answer: The count is variable depending on the size option you choose.
Ronald W Tew · February 24, 2019
Question: The description is confusing (all 100 are "3mm" diameter?). what diameters and quantity are included?
Answer: I got 10, and all were this stated size.

Question: If I put 4 of these on a small wooden sign (11"x7") would it be able to hold it up?
Answer: I think so.

Answer: If they are as strong as the neodymium magnets, then yes, I think it will. I have the tiny size for a magnet board and they are pretty strong.

WarrantyThis magnet includes a 10-year warranty for its magnetic strength, provided it is used under normal conditions. Usage in environments with elevated temperatures, significant vibration, or intense opposing magnetic fields will render this warranty null and void. It is also not suitable for use outdoors or in areas with high humidity or salt content, unless additional protective insulation measures are implemented.
