Why Iron Is MagneticOther Magnetic ElementsMagnetic and Nonmagnetic SteelMetals That Aren't MagneticSteel is an iron-based alloy. Most forms of steel, including stainless steel, are magnetic. There are two broad types of stainless steels which display different crystal lattice structures from one another. Ferritic stainless steels are iron-chromium alloys that are ferromagnetic at room temperature. While normally unmagnetized, ferritic steel become magnetized in the presence of a magnetic field and remain magnetized for some time after the magnet is removed. The metal atoms in ferritic stainless steel are ar…

How magnets are made Bunting - eMagnets

The Neodymium magnet is made up of multiple domains in simple terms, think of these as miniature magnets that make up the entire magnet . A very small proportion of domains are ‘weak’ and these ‘relax’ soon after the magnetisation. This is natural and cannot be avoided. The output drop is very small much less than 0.5 % typically and occurs very soon after being magnetised to
