Question

The relative permeability of iron is $6000$. Its magnetic susceptibility is

• A. $5999$
• B. $6001$
• C. $6000 \times 10^{-7}$
• D. $6000 \times 10^{7}$

Answer 1

Answer: (A)

$5999$

Answer 2

Relative permeability of iron,
$\mu _{r} = 6000$
Magnetic susceptibility
$\chi_{m} = \mu_{r} - 1 = 5999$.
