The $\chi - 1/T$ graph for an alloy of paramagnetic nature is shown in the figure. The Curie constant is,then....$K$.

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?

The dimensions of magnetic intensity are

The susceptibility of $Al$ is $2 \times 10^{-5}$. The percent increase in the magnetic field when the space within a current-carrying toroid is filled with $Al$ is:

What is the magnetic susceptibility of a medium if its relative permeability is $0.85$?

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:
