How strong are rare earth magnets? VCElements
to compare the strength of magnets. But before looking at the strongest magnets, it’s essential to understand how to measure magnetic strength., measured in mega-gauss-oersteds , is one of the primary indicators of magnetic strength. It is a multiplication of two measurements: a magnet’s remanence and its coercivity.To become magnets, ferromagnetic substances need to enter the magnetic field of an existing magnet.
Each magnet has a grade, which typically denotes its strength. For example, a neodymium magnet of grade N42 has a strength of 42MGOe. Neodymium magnets are typically composed of one-third neodymium, along with iron and boron. Some of the neodymium in magnets can be replaced with praseodymium, another rare earth material. For this reason, neodymium magnets are also known as NdPr magnets.
