Which of the following statement is correct?a)Diamagnetic materials sh...
- In Diamagnetic materials, a very weak form of magnetism that is non-permanent exists only while the external field is being applied
- The relative permeability is small and less than unity
- In paramagnetic materials, each atom possesses a permanent dipole moment by virtue of incomplete cancellation of electron spin and orbital magnetic moments
- At the macroscopic level, these magnetic moments cancel out each other and there is no net magnetism in the absence of an electric field

Diamagnetic materials show magnetism only in the externally applied magnetic field.
Paramagnetic materials show magnetism only in the externally applied magnetic field.
Ferromagnetic materials show magnetism only in the externally applied magnetic field.
The correct answer is option 'D' - Both a and b.
Explanation:
Diamagnetic materials are those materials that have no unpaired electrons and are not attracted to a magnetic field. They do not retain any magnetism after the external magnetic field is removed. Diamagnetic materials show magnetism only in the presence of an externally applied magnetic field. When a diamagnetic material is placed in a magnetic field, it generates a magnetic field in the opposite direction. This opposing magnetic field weakens the overall magnetic field, resulting in a repulsive force between the material and the magnet. Examples of diamagnetic materials include water, copper, gold, and bismuth.
Paramagnetic materials are those materials that have unpaired electrons and are weakly attracted to a magnetic field. They have a net magnetic moment in the direction of the externally applied magnetic field. When a paramagnetic material is placed in a magnetic field, the external magnetic field aligns the magnetic moments of the unpaired electrons, resulting in a weak attraction. Paramagnetic materials do not retain any magnetism after the external magnetic field is removed. Examples of paramagnetic materials include aluminum, magnesium, and oxygen.
Ferromagnetic materials are those materials that have unpaired electrons and are strongly attracted to a magnetic field. They have a net magnetic moment in the direction of the externally applied magnetic field. Unlike diamagnetic and paramagnetic materials, ferromagnetic materials can retain their magnetism even after the external magnetic field is removed. They have a high magnetic susceptibility and exhibit permanent magnetism. Examples of ferromagnetic materials include iron, nickel, and cobalt.
Therefore, the correct statement is option 'D' - Both a and b. Diamagnetic materials and paramagnetic materials show magnetism only in the externally applied magnetic field.
Paramagnetic materials show magnetism only in the externally applied magnetic field.
Ferromagnetic materials show magnetism only in the externally applied magnetic field.
The correct answer is option 'D' - Both a and b.
