5. A uniform external magnetic field, created by something you don't see here, points upward, in the plane of the paper as shown below (this is different from the field created by the wire). The wire is perpendicular to the paper, represented by the empty circle. When the wire carries current, there is a NET MAGNETIC FIELD AT POINT 2 OF ZERO. a. B 109 What is the direction of the current in the wire? Justify. b. C. Point 1 is the same distance from the wire as point 2. Use a vector addition diagram to draw the net magnetic field vector at point 1. Point 3 is twice as far from the wire as point 2. Use a vector addition diagram to determine the net magnetic field at point 3. It will help to draw the vector sizes proportional to their magnitude.
