Magnetic susceptibility of ferromagnetic material – Rankers Physics

Magnetic Properties of Matter: Practice Problem & Solution

The relative permeability of a ferromagnetic material is \( 5999 \). Its magnetic susceptibility is
\( 6000 \)
\( 6000 \times 10^{-7} \)
\( 5998 \)
\( 5.999 \times 10^7 \)

Solution Explained:

To solve this problem, we apply the core principles of Magnetic Properties of Matter. Understanding the underlying formula is key to arriving at the correct answer below:

The relation between relative permeability and magnetic susceptibility is \( \mu_r = 1 + \chi_m \). Therefore, \( \chi_m = \mu_r - 1 = 5999 - 1 = 5998 \).
