Is Zinc Magnetic? Exploring Its Diamagnetic Properties
Zinc, with the symbol Zn and atomic number 30, is a bluish-white, lustrous metal, although most commercial grades appear dull. It is somewhat less dense than Iron and is hard and brittle at most temperatures but becomes malleable between 100 and 150°C. Above 210°C, Zinc becomes brittle again and can be pulverized by beating. As a metal, Zinc is a fair conductor of electricity and has relatively low melting and boiling points. It reacts readily with acids, alkalis, and other non-metals.
Besides its industrial uses, Zinc is an essential trace element for humans, animals, plants, and microorganisms and is necessary for prenatal and postnatal development. Major uses of Zinc include galvanizing iron and steel to protect against corrosion and in manufacturing brasses and alloys for die-casting. Zinc forms a protective coating of its oxide when exposed to the atmosphere, making it more resistant to corrosion than iron, thus corroding at a much slower rate. The Zinc coating is typically applied through hot-dip galvanizing or electrogalvanizing. Addressing the question “is Zinc magnetic,” the answer is no. Zinc is classified as a diamagnetic substance, meaning it is slightly repelled by magnetic fields, and thus, permanent magnets cannot adhere to Zinc.
