A compass originally points north; at this location the horizontal component of the Earth's magnetic field has a magnitude

of 2 × 10−5 T. A bar magnet is aligned east–west, pointing at the center of the compass. When the center of the magnet is

0.25 m from the center of the compass, the compass deflects 70°. What is the magnetic dipole moment of the bar magnet?
