A bar magnet 10 cm long has cross-sectional area $2c{m}^{2}2\; \backslash \; cm^2$ and magnetic dipole moment of $10A\mathrm{.}{m}^{2}10\; \backslash \; A.m^2$ . The magnetization of its material, assumed to be uniform, is

An iron rod of volume $10^{-4}{m}^{3}10^\{-4\}\; \backslash \; m^3$ acquires a magnetic moment of $25A\mathrm{.}{m}^{2}25\; \backslash \; A.m^2$ when placed inside a solenoid whose windings carry a current of 0.5 A. The magnetization of the rod (in A/m), assumed to be uniform, is
