A single piece of wire carrying current I is bent so it includes a circular loop of radius a, as shown in Fig. 26. Find an expression for the magnetic field at the loop center. You and a friend get lost while hiking, so your friend pulls out a magnetic compass to get re-oriented. However, youre standing right under a power line carrying 1.5 kA toward magnetic north; its 10 m above the compass. The horizontal component of Earths magnetic field at your latitude points northward and has magnitude 0.24 G. Will the compass help you find your way?
