A bar magnet with magnetic dipole moment 0.6A · m2 lies on the negative x axis
A bar magnet with magnetic dipole moment 0.6A · m2 lies on the negative x axis, as shown in the figure below. 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 3.5 cm, connected to batteries not shown. The distance from the center of the coil to the center of the compass is 8.9 cm. The distance from the center...

3. A coil consists of 130 circular loops of wire of radius 4.4 cm. A current of 0.46 A runs through the coil, which is oriented vertically and is free to rotate about a vertical axis (parallel to the z-axis). It experiences a uniform horizontal magnetic field in the positive x-direction. When the coil is oriented parallel to the x-axis, a force of 1.2 N applied to the edge of the coil in the positive y-direction can keep it from...
