The heart produces a weak magnetic field that can be used to diagnose certain heart problems. It is a dipole field produced by a current loop in the outer layers of the heart. It is estimated that the field at the center of the heart is 86 . What current must circulate around an 8.0--diameter loop, about the size of a human heart, to produce this field? What is the magnitude of the heart's magnetic dipole moment?
