The document outlines the magnetic properties of materials, classifying them into categories such as diamagnetic, paramagnetic, ferromagnetic, ferrimagnetic, and antiferromagnetic, each defined by their unique behaviors in magnetic fields. It describes concepts like magnetic field, magnetic field strength, magnetic flux density, and magnetic moments, which are fundamental to understanding these properties. For further details, the document suggests visiting a provided link for more comprehensive information.

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 /m2)
• 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
