nt FULL SCREEN PRINTER VERSION NEXT Cnapter 41, ProDiem b2 A smail compass is held horizontally, the center of its needle a distance of 0.240 m directly north of a long wire that is perpendicular to the earth's surface. When there is no current in the wire, the compass needle points due north, which is the direction of the horizontal component of the earth's magnetic field at that location. This component is paraliel to the earth's surface. When the current...
