Q1

The relationship between the magnetic susceptibility \((\chi )\) and the magnetic permeability \((\mu )\) is given by :
( \({\mu }_{0}\) is the permeability of free space and \({\mu }_{\mathrm{r}}\) is relative permeability)

[JEE Main 2025, 2 Apr (Shift 1)]

a

\(\chi =\frac{\mu }{{\mu }_{0}}-1\)

b

\(\chi =\frac{{\mu }_{\mathrm{r}}}{{\mu }_{0}}+1\)

c

\(\chi ={\mu }_{r}+1\)

d

\(\chi =1-\frac{\mu }{{\mu }_{0}}\)
