MCQ (More than One Correct Answer)

-0

If $$\chi $$ stands for the magnetic susceptibility of a substance, $$\mu$$ for its magnetic permeability and $$\mu$$₀ for the permeability of free space, then

for a paramagnetic substance : $$\chi $$ < 0, $$\mu$$ > 0

for a paramagnetic substance : $$\chi $$ > 0, $$\mu$$ > $$\mu$$₀

for a diamagnetic substance : $$\chi $$ > 0, $$\mu$$ < 0

for a ferromagnetic substance : $$\chi $$ > 1, $$\mu$$ > $$\mu$$₀
