Question : 9
Total: 30
Out of the two magnetic materials, 'A' has relative permeability slightly greater than unity while 'B' has less than unity. Identify the nature of the materials ' A
Solution:
In paramagnetic and ferromagnetic materials, the relative permeability is more than unity; in diamagnetic materials, it is less than unity. Additionally, magnetic susceptibility is positive for paramagnetic and ferromagnetic materials while being negative for diamagnetic materials.
So A: paramagnetic B: Diamagnetic
Susceptibility for A: positive for B: negative
So A: paramagnetic B: Diamagnetic
Susceptibility for A: positive for B: negative
