You and a friend get lost while hiking, so your friend pulls out a magnetic compass to get re-oriented. However, you?re standing right under a power line carrying 1.5 kA toward magnetic north; it?s 10 m above the compass. The horizontal component of Earth?s magnetic field at your latitude points northward and has magnitude 0.24 G. Will the compass help you find your way?
