Block Magnet Powerful Magnets for Neodymium Magnets Experiments

Standard sizes ship within 2 weeks. custom-made sizes and grades are always available.A permanent magnet is a magnet that is permanent, in contrast to an electromagnet, which only behaves like a magnet when an electric current is flowing through it.Permanent magnets are made out of substances like magnetite (Fe3O4), the most magnetic naturally occurring mineral or neodymium, Samarium cobalt, a powerfully magnetic synthetic substance.The Earth itself is a huge permanent magnet, though its magnetic field is quite weak relative to its size. Humans have used the magnetic field of the Earth for navigation since the compass was invented in ancient China.Even the most powerful permanent magnet is not as strong as the strong electromagnets, so their applications are limited, but they still have very wide applications, magnets can be found everywhere, including your hard disk, ATM and credit cards, speakers and microphones, electric motors, and toys.Every permanent magnet generates a magnetic field, which circulates around the magnet in a distinct pattern. The size of the magnetic field is related to the size of the magnet and its strength. GME Magnets offers the highest quality Neodymium magnets with consistent performance and the lowest price. Our Neodymium magnets are designed and manufactured to meet quality standards using the latest technology. Here introduce a super strong permanent magnet that is very popular in European magnet market, especially in German.SpecificationF5*5*5mmMaterial GradeNeodymium N42Length5mmWidth5mmThickness5mmCoatingNiCuNiColorSilver ToneMagnetized directionthrough thicknessPull strength / Magnetic Force3KGMOQ30000 pcsLeading Time18-23 working daysSampleYesCertificateISO2000, TS16949, RoHS, CE & SGSPaymentT/T, PayPal, Western UnionMagnetic Characteristics of N42GRADERemanenceCoercive ForceIntrinsic CoerciveMax Energy ProductWorking Temp.(Br)(bHc)(iHc)(BH)maxTw(ºC)TKGsKA/mKOeKA/mKOeKJ/m³MGOe N421.28-1.3412.8-13.4≥923≥11.6≥955≥12318-34240-43≤80  /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
