Stainless steel-Are All Metals Magnetic or Attracted by Magnets?
We deal with a broad range of new projects for diverse application. One of the common misconceptions we encounter is the belief that all metals can be attracted by magnets or that all metals are magnetic. It is common knowledge that magnets don’t attract materials like wood, plastic, glass but, when it comes to metals, things are often less straightforward.Any material can be classified in terms of its magnetic behaviour when exposed to an external magnetic field. Although many think materials are either magnetic or non-magnetic, there are, in fact, five (5) categories of magnetic behaviour. But, for most of the elements of the periodic table, diamagnetism and paramagnetism are two of the most common types of magnetism (at room temperature). To properly define how a material responds to an applied magnetic field, we introduce a term called Magnetic Susceptibility, which is a value that indicates the degree of magnetization of a material in response to the applied magnetic field (i.e. it indicates to what extent the material gets magnetised by the applied field). Every material will have a Magnetic Susceptibility value. Relative magnetic permeability is another value that is used.
