Why susceptibility of diamagnetic materials is negative?
As we have discussed in the earlier articles, that relative permeability of diamagnetic materials is lesser than 1 and also there is a relation between relative permeability (μr)and susceptibility (χ):
μr = 1 + χ
where is μr
or χ = μr – 1
and μr is less than 1
therefore, χ is negative
