what are the magnetic properties of solids???
Answers
Answer:
These magnetic moments come from two types of motion of electrons:
The orbital movement around the nucleus of an atom.
When the electron spins around its own axis.
On the basis of the magnetic properties solids can be classified as follows:
PropertiesDescriptionAlignment of magnetic dipolesExamplesApplicationDiamagneticThey 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 appliancesFerromagneticStrongly 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, V2O3 etc.–FerrimagneticPossess small net magnetic momentsUnequal number of parallel and antiparallel arrangement of magnetic momentsFe3O4
Answer:
The magnetic properties of a solid are the result of the magnetic property of the atoms or ions of these solids. More specifically the magnetism and magnetization of a solid will depend on the movement of electrons in an atom. It can thus be said that each electron of an atom behaves like a magnet, lending the whole solid its magnetic property.
