Explain the magnetic properties of solids.

Answer»

 On the basis of the magnetic properties solids can be classified as follows:

PropertiesDescriptionAlignment of magnetic dipolesExamplesApplication
DiamagneticThey are weakly repelled by the magnetic fieldsAll the electrons in the orbitals are paired and are completely filled.NaCl, BenzeneBehaves like an insulator.
ParamagneticThey are weakly attracted by the magnetic fields.Contains at least one unpaired electron in the orbital.O2, Cu2+ etc.Electronic appliances
FerromagneticStrongly attracted by the magnetic field.
It can be magnetized permanently
Consists of unpaired electrons, all having the same directionCobalt, nickel, CrO2 etc.CrO2 is commonly used in making cassette recorder.
AntiferromagneticNet magnetic moment is zero.Dipole moments are arranged in a compensatory wayNiO, MnO, V2Oetc.
FerrimagneticPossess small net magnetic momentsUnequal number of parallel and antiparallel arrangement of magnetic momentsFe3O4
