Deflecting a compass needle When you bring a current-carrying wire down onto the top of a compass, aligned with the original direction of the needle and 3 mm above the needle, the needle deflects by 9 = 8 degrees (see the figure). B Earth (a) Which of the following statements are correct? Select all that apply. C] The magnetic eld under the wire, due to the current, points to the East. C] The magnetic eld under the wire, due to the current, points North. C] The magnetic eld under the wire, due to the current, points to the West. C] Conventional current in the wire is flowing downward (South). C] Conventional current in the wire flows upward (North). [:1 Electron current in the wire is flowing upward (North). (b) Calculate the amount of conventional current flowing in the wire. The measurement was made at a location where the horizontal component of the Earth's magnetic field is BEarth z 2 x 10'5 tesla. :11; Additional Materlals [El eBook
