Magnetic Properties of Solids: Solids can be classified on the basis of their behaviour towards magnetic filed into following types- Diamagnetic Substances: Diamagnetic Substances are those substances which are weakly repelled by a magnetic field. Example- Ni(Co)4, K4, NaCl. Diamagnetic substances have all their electrons paired, i.e., absence of unpaired electrons so that they possess zero magnetic moment. Paramagnetic Substances: The substances which have permanent magnetic dipoles and are attracted by the magnetic field are known as paramagnetic substances. These consist of atoms, ions or molecules having one or more unpaired electrons. The common examples are Cu2+, Fe3+, Cr3+, O2, … Continue reading Magnetic Properties of Solids
