- 1. Magnetic property ofMaterials
- 2. Magnetic properties ofmaterial 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 magneticmaterial • 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: Retainsmagnetism 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: Inanti-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
