Please wait for the animation to completely load.
Three loops are shown in a region where the magnetic field is changing (position is given in meters and time is given in seconds). Blue indicates the magnetic field is directed into the screen and red indicates it is directed out of the screen. The intensity of the color represents the magnitude of the field. At any instant of time, the red and blue "fields" have the same magnitude. Restart.
For each of the following times, is there a current in each loop (A, B, and C) and, if there is a current, is it flowing clockwise or counterclockwise? Explain.
