Explanation:
The difference between parallel and anti parallel alignment of the z component of an electron's spin magnetic dipole moment is given by
where μ= dipole moment B= strength of magnetic field and θ= angle between direction of magnetic field and dipole
here θ_2 and θ_1 are 180 and 0° respectively.
here μ is bohr magnetron or magnetic moment of an electron = 9.27×10^{-24}
put this value we get
