Acompass originally points north; at this location the horizontal component of the earth's magnetic field has a magnitude of 3.6 ✕ 10−5 t. a bar magnet is aligned east–west, pointing at the center of the compass. when the center of the magnet is 0.38 m from the center of the compass, the compass deflects 64°. what is the magnetic dipole moment of the bar magnet? (enter the magnitude.)
