A small compass is held horizontally, the center of its needle has a distance of 0.270 m directly northof a long wire that is perpendicular to the Earth's surface. When there is no current in the wire, thecompass needle points due north, which is the direction of the horizontal component of the Earth'smagnetic field at that location. This component is parallel to the Earth's surface. When the current inthe wire is 26.3 A, the needle points 22.9 east of north.(a) Does the current in the wire flow toward or away from the Earth's surface? ( 2 marks)(b) What is the magnitude of the horizontal component of the Earth's magnetic field at the location ofthe compass? (3 marks)
