The answers are

11. B 12. E 13. D 14. B 15. A

Thanks in advance

Two opposite currents of 1 A each are separated by a distance 2 meters as shown. The current on the left is coming out of the page (+1} toward you, and the current on the right is going into the page {-1} away from you as shown. Consider the poi nts A, B, and c at the locations shown. 1 m 1 in 1 m 1 m on -------oB-------- 0c 1 A 1 t 11. At which point is the magnetic eld magnitude highest? a. Point A b. Point B c. Point C d. PointsAand C e. All three are the same 12. In which direction is the magnetic eld at point A? a. It is zero. in. +x {right} c. x {left} d- +v lupi e. qr (down) 13. In which direction is the magnetic field at point B? a, It is zero. h. +x {right} c. at {left} d. +r [uni e. qr [down} 14. What is the direction of the magnetic force on the right wire caused by the left one? a. It is zero. b. +3: {right} c. -x {left} d- or [uni e. -y {down} 15. If an electron were released from rest at point B, which wet}I would it start to move due to Its interaction with the currents? a. It wouldn't move. b. +x {right} c. -Jt {left} d- Mum e. -y[down}
