A magnetic dipole with a dipole moment of magnitude 18.0 mJ/T is released from rest in a uniform magnetic field of magnitude 49.0 mT. Assume the magnetic force does not impede the rotation of the dipole. When the dipole rotates through the orientation where its dipole moment is aligned with the magnetic field, its kinetic energy is 0.710 mJ. What is the initial angle between the dipole moment and the magnetic field
