A long current-carrying wire oriented North-to-South lies on the table with a compass under the wire and the needle distance r=1mm from the wire. With the current running in the wire, the compass needle deflects 0=130 to the East. The picture below shows a view from the top. The horizontal component of the Earth's magnetic field at that location is BEarth= 2.6e-05T. d . A Point A is located on the table top distance d=1.3cm away from the wire. What is the direction of the magnetic field due to the wire at location A? O Upwards from the table O Upwards and to the right O To the right away from the wire along the table surface O To the left towards the wire along the table surface O Downwards into the table O Downwards and to the left O Downwards and to the right O Upwards and to the left X What is the magnitude of the magnetic field due to the wire at location A? BA = TApology , the figure looks confusing . I overlooked that the compass is "under the wire" N VI A H H S Correct, the current in the wire should flow from South to North . Using right-hand rule , the direction of the magnetic field due to the wire at location A is upwards from the table
