Magnetic Properties of Materials | Physics

Magnetic Field: The magnetic field is an imaginary line of force around a magnet which enables other ferromagnetic materials to get repelled or attracted towards it.

1. Magnetic property of Materials

2. Magnetic properties of material can be classified as: Magnetic field : The imaginary lines of force around a magnet Magnetic field strength : H = nL /l (A/m)

3. Magnetic flux density : Magnetic lines passing through per square metre of a substance B=μ X H (Tesla or weber /m 2 ) Magnetic Moments: The rotational force experienced by a magnet when placed in a magnetic field perpendicular to its magnetic axis is defined as the magnetic moment of a magnet.  

4. Classification of magnetic material Diamagnetic: Net magnetic moment is zero due to the alignment of magnetic moment in the opposite direction H Paramagnetic: Very little magnetic susceptibility

5. Ferro-Magnets: Retains magnetism even when external field is removed because of the parallel alignment of the electron moment. Ferri -Magnets: Some magnetic domains in ferri -magnetic material points in the same direction while some point in the opposite direction.

6. Anti-Ferromagnetism: In anti-ferromagnetic material, the magnetic moments of atoms or molecules usually related to the spin of the electrons, align in a regular pattern with neighbouring spins in opposite directions. MnO is an example of anti-ferromagnetism

7. Classification of periodic elements based on magnetic properties
