وہ مادے جن کی پارگمیتا خالی جگہ کی پارگمیتا سے کم ہوتی ہے ان کو کیا کہا جاتا ہے؟
Explanation
  • Substances with permeability less than that of free space (μ₀) are called diamagnetic materials.
  • These materials are weakly repelled by magnetic fields and have a relative permeability (μr) less than 1.
