At a certain location, Earth's magnetic field of 44 µT ishorizontal and directed due north. Suppose the net field is zeroexactly 11 cm above a long, straight, horizontal wire that carriesa constant current. What is (a) the magnitude of the current (in A)and (b) the angle between the current direction and duenorth?
