A magnet in the form of a cylindrical rod has a length of 4.36 cm and a diameter of 1.32 cm. It has a uniform magnetization of 7.66 x 103 A/m. What is its magnetic dipole moment? Number i Units Suppose that the saturation magnetization Mmax of the ferromagnetic metal nickel is 6.01 x 105 A/m. Calculate the magnetic moment of a single nickel atom. (The density of nickel is 8.90 g/cm3 and its molar mass is 58.71 g/mol.) Number Units What is the energy difference between parallel and antiparallel alignment of the z component of an electron's spin magnetic dipole moment with an external magnetic field of magnitude 0.28 T, directed parallel to the z axis?
