Assume that each iron atom has a permanent magnetic moment equal to 2 Bohr magnetons (1 Bohr magnetic equals 9.27 × 10^-24 A-m^2). The density of atoms in iron is 8.52 × 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.
