A compass originally points North; at this location the horizontal component of the Earth's magnetic field has a magnitude of 2e-5 T. A bar magnet is aligned East-West, pointing at the center of the compass. When the center of the magnet is 0.29 m from the center of the compass, the compass deflects 70 degrees. What is the magnetic dipole moment of the bar magnet? = A·m2
