A planet with earth like magnetic field can be considered as a bar magnet. Suppose, we have such a bar magnet. We will treat it a magnetic dipole. Its dipole moment is given by the i = Hyj+ µzk which remains unchanged without the application of external magnetic field. Suppose, a uniform magnetic field given by, B = ((-62.0) j+ (–28.0) k) × 10º Tesla. Some neutron stars can generate such intense magnetic field. When this magnetic field is applied, the bar magnet starts to rotate. At some instant during rotation, consider it as "position 1" of the dipole, it's torque is T = (-1058.4185740306602) × 1020.0 i N · m and potential energy is U = -3290.0787410253424 × 1020.0 J.
