Nonmagnetic refers to materials that do not possess magnetic properties. However, there are several synonyms that can be used to describe such materials. One alternative term is diamagnetic, which denotes substances that generate a weak magnetic field in the opposite direction when exposed to an external magnetic field. Another synonym is nonferromagnetic, referring to materials that lack magnetic properties similar to those found in iron or iron alloys. Paramagnetic is yet another suitable replacement and describes materials that exhibit a weak attraction to magnetic fields. Thus, these synonyms help to convey the concept of materials lacking magnetic properties, offering alternative ways to describe the nonmagnetic nature of certain substances.
