Problem 68

Figure 22.68 shows a long straight wire just touching a loop carrying a current I1 . Both lie in the same plane. (a) What direction must the current I2 in the straight wire have to create a field at the center of the loop in the direction opposite to that created by the loop? (b) What is the ratio of I1 / I2 that gives zero field strength at the center of the loop? (c) What is the direction of the field directly above the loop under this circumstance?
