Two long parallel wires are separated by 9.0 cm. The current in wire-1 is twice the current in wire-2 and they are running in the same direction. Find the point between the two wires where the net magnetic eld is zero. Answer it by the distance from the point to wire-1. 03cm 0 6cm 0 5.6cm O 5cm 0 4.8 cm Question 17 5 pts Two semicircular loops are placed close to each other as shown. The currents in the left |00p is 4.0 A and in the right loop is 4.0 A. What is the direction of the magnetic eld in the center point p? 0 Zero 0 to the right 0 out of the page 0 None is correct 0 Into the page Question 18 When using Ampere's Law, which currents can and must be included in the calculation? 0 only those currents generated by positive charges O None are correct. 0 all currents O only those currents which form a closed loop
