A bar magnet with magnetic dipole moment 0.51 A m2 lies on the negative x-axis, as shown in the diagram. A compass is located at the origin. Magnetic North is in the negative z direction. Between the bar magnet and the compass is a coil of wire of radius 1.5 cm, connected to batteries not shown in the picture. The distance from the center of the coil to the center of the compass is 9.9 cm. The distance from the center of the bar magnet to the center of the compass is 22.5 cm. A steady current of 0.931 amperes runs through the coil. Conventional current runs clockwise in the coil when viewed from the location of the compass. Despite the presence of the coil and the bar magnet, the compass points North. Which end of the bar magnet is closer to the compass? 1 —Select— North South Check all of the following statements that are correct:2At the location of the compass, the magnetic field due to the magnet is equal in magnitude to the magnetic field due to the coil. At the location of the compass, the net magnetic field is equal to the magnetic field of the Earth. Because not all parts of the magnet are the same distance from the compass, treating the magnet as a dipole located at the center of the magnet is an approximation. The magnetic dipole moment of the coil is equal to the magnetic dipole moment of the compass. It isn’t necessary to take the magnetic field of the magnet into account, since the coil is in between the magnet and the compass.How many turns of wire are in the coil? number of turns = 3 .
