$A$ magnetizing field of $2 \times 10^3 \, A/m$ produces a magnetic flux density of $8 \pi \, T$ in an iron rod. The relative permeability of the rod will be -

The magnetic moment produced in a substance of $1 \ gm$ is $6 \times 10^{-7} \ A \cdot m^2$. If its density is $5 \ gm/cm^3$,then the intensity of magnetization (in $A/m$) will be:

$ \chi_{1} $ and $ \chi_{2} $ are the magnetic susceptibilities of a paramagnetic material at temperatures $ T_{1} \ K $ and $ T_{2} \ K $ respectively. Then:

The magnetic susceptibility of the material of a rod is $499$. Permeability of vacuum is $4 \pi \times 10^{-7} \ H/m$. The absolute permeability of the material of the rod in $H/m$ is:

The magnetization of a bar magnet of length $5 \ cm$,cross-sectional area $2 \ cm^2$ and net magnetic moment $1 \ A \cdot m^2$ is:

An iron rod of cross-sectional area $0.2 \, cm^2$ is subjected to a magnetizing field intensity of $1600 \, A \cdot m^{-1}$. If the magnetic flux produced in the rod is $2.4 \times 10^{-5} \, Wb$, what is the magnetic susceptibility of the material of the rod?
