- Question 1: When an external magnetic flux through a conducting loop decreases in magnitude, a current is induced in the loop that creates its own magnetic flux through the loop. How does that induced magnetic flux affect the total magnetic flux through the loop? O It does not affect the total magnetic flux. O It decreases and then increases the total magnetic flux. OIt increases the total magnetic flux. OIt increases and then decreases the total magnetic flux. O It decreases the total magnetic flux. Part (a) Some additional information, which is not included in the video, is that the SI unit of magnetic flux is the weber, denoted Wb. Using that information and the contents of the video, solve this numerical problem: A conducting loop, with a resistance of 2.0 Q2, encloses magnetic flux that is increasing at the rate of 2.0 Wb/s.
