Problem 18: A student uses a compass and a current-carrying wire to measure the horizontal component of the magnetic field in the laboratory. (This field includes the magnetic field of the Earth, but it may also be affected by nearby electronic equipment or magnetized materials.) Initially the compass is aligned so that the tip of the red arrow points to 0°, magnetic north. A wire is aligned north-south at a distance 5.5 cm directly beneath the compass, as shown. A current is initiated in the wire, and when it is increased to 7.5 A, the compass needle points to 30°. 320 340 007 081 091
