Magnetic Properties of Ma question bank (Physics)

A magnetizing field of $10^3\ \text{A/m}$ produces a magnetic flux density $4\pi$ T in an iron rod. The relative permeability of the rod will be (permeability of free space $\mu_0 = 4\pi \times 10^{-7}$ SI units)

A magnetic material has a relative permeability $(\mu_r)$ of $6001$. If it is placed in a magnetizing field (magnetic intensity) of $H = 2000\ \text{A/m}$, The total magnetic induction $(B)$ inside the material is nearly equal to
$\mu_0 = 4\pi \times 10^{-7}\ \text{T}\cdot\text{m/A}$
