Problem 9: You are standing upright on top of a very long thin horizontal straight current- carrying wire. The tip of your nose is exactly 1.75m above the wire and the magnetic field vector produced by the wire at the tip of your nose is 3.2mT in magnitude, pointing in an eastward direction. What is the current in the wire and in which direction is it flowing? Hints: (1) Review: https://tinyurl.com/ybu8k6tl. (2) Make a drawing which shows the circular magnetic field lines in the plane of the drawing. (3) What is the direction of the current flow and the wire, relative to the plane of this drawing? (4) Do not confuse the direction " Up" with the direction "North"; see: https://tinyurl.com/ydyjpqva. (A) 28KA flowing in northward direction (B) 56KA flowing in westward direction (C) 56KA flowing in northward direction (D) 28KA flowing in southward direction (E) 56KA flowing in eastward direction
