Neodymium magnets are the strongest permanent magnets available and, even if youve never heard of them before, you probably use them every day. For example they are over ten times stronger than ceramic magnets, so you might replace a ceramic magnet with a much smaller neodymium magnet and generate the same (or more!) Theyre sometimes called NdFeB, or Neo magnets, and despite being so strong, theyre also lightweight, which is why theyre popular for a wide variety of applications. More than one-third of the output of theneodymium magnets is used to manufacture various permanent magnet motors. Neos are also susceptible to temperature differences and can crack or lose their magnetism in higher temperatures, usually above 176 degrees Fahrenheit. Many of these magnets have a magnetic field of around 1 tesla! This means that the highest temperature that these magnets can be used at is the very low 140 degrees Fahrenheit.
