Difference between Diamagnetism and Ferromagnetism

Difference between Diamagnetism and Ferromagnetism

The ferromagnetic substances spin, magnetic moments have a large contribution. These substances consist of a large number of small units that are known as domains. These domains experience torque when a ferromagnetic substance is exposed to an external magnetic field. Due to this, the domains rotate and remain parallel to the direction of the field. The electron’s orbital motion gives rise to an orbital magnetic moment. In addition to this, the electrons tend to spin around their own axis, creating a spin magnetic moment. Electrons in an atom can have a clockwise or anticlockwise spin. In a similar way, the electrons can revolve around the nucleus in a clockwise or anticlockwise direction.

                              Diamagnetism                               Ferromagnetism
1)      Diamagnetic substance can be in a solid, liquid or gaseous state.

2)      Diamagnetic subatance are feebly repelled by magnets.

3)      They move from stronger to weaker parts of the field when placed in a non-uniform magnetic field.

4)      Temperature has no impact on diamagnetic subatance.

5)      In a diamagnetic subatance, the magnetic moment of every atom is calculated to be zero.

6)      A material that turns at a right angle to the field by producing a manetic response opposites to the applied is called diamagnetic materials.

7)      Examples of diamagnetic subtance is silver, gold, murcury.

 

1)      Ferromagnetic substance are always in a solid state.

2)      Ferromagnetic substance are strongly attracted by magnets.

3)      They move from the weaker to the stronger part of the field when placed in non-uniform magnetic field.

4)      They can turn into paramagnetic substance if heated above the curie point.

5)      These substances do not lose their magnetism when the external magnetic field is removed.

6)      Within the paramagnetic class of materials, is a special classification of materials called ferromagnetic materials.

7)      Examples of ferromagnetic subtance is iron, cobalt, nickel etc.
