Let us see whether silica sand is magnetic or not. Silica sand is not magnetic as it majorly composes of silica which is diamagnetic. Some grains of silica sand may show weak magnetic behavior due to impurities and fine particles of iron. Silica sand grains are perfectly crystalline, and silica has two unpaired electrons in a 3p orbital …
