Question

The relation between ${\mu }_r$ and $\chi$ is :

• A. ${\mu }_r=1+\chi$
• B. $\chi ={\mu }_r+1$
• C. $\chi ={\mu }_0{\mu }_r$
• D. $\chi ={\mu }_r/{\mu }_0$

Answer 1

The correct option is A ${\mu }_r=1+\chi$

${\mu }_r$ stands for relative permeability and $\chi$ stands for susceptibility and relation between them is given by,

${\mu }_r=1+\chi$
