I'm going over my practice physics exam and came to this question Two concentric, circular loops of wire lie in the plane of the paper. The outer loop carries a current I. pick the right answer. I was able to get the choose to two: a) If I is clockwise and increasing the induced current of the inner loop will be clockwise. b) If I is counterclockwise and decreasing, the induced currecnt in the inner loop will be counterclockwise. i know that answer is b, but i dont see how choice a) is wrong.
