The relative permeability of iron is $5500$. What will be its magnetic susceptibility?

The magnetic moment produced in a sample of $2 \text{ g}$ is $8 \times 10^{-7} \text{ A} \cdot \text{m}^2$. If its density is $4 \text{ g/cm}^3$, then the magnetization of the sample is: (in $\text{ A/m}$)

The magnetic moment of a sample of $2 \text{ g}$ is $8 \times 10^{-7} \text{ Am}^2$. If its density is $4 \text{ g/cm}^3$,then the magnetization of the sample in $\text{Am}^{-1}$ is:

An iron rod is placed parallel to a magnetic field of intensity $2000 \text{ A/m}$. The magnetic flux through the rod is $6 \times 10^{-4} \text{ Wb}$ and its cross-sectional area is $3 \text{ cm}^2$. The magnetic permeability of the rod in $\text{Wb/(A} \cdot \text{m)}$ is:

The dimensions of magnetic intensity are

The magnetic susceptibility is defined as:
