Assume that each iron atom has a permaanent magnetic moment equal to 2 Bohr magnetons `(1 Bohr magneton equals 9.27 xx 10^(-24) A m^2)`. The density of atoms in iron is `8.52 xx 10^28 atoms m^(-3)`. (a) Find the maximum magnetization `I` in a long cylinder of iron. (b) Find the maximum magnetic field `B` on the axis inside the cylinder.
