Problem 29.2: Graph current versus time

Please wait for the animation to completely load.

A loop is shown in a region where there is a magnetic field (position is given in meters and time is given in seconds). Blue indicates where the magnetic field is directed into the screen and red indicates where it is directed out of the screen. Restart.

  1. Construct a qualitative graph of current induced in the loop vs. time. Indicate on your graph the time when the current reaches its maximum and minimum values. Consider the current to be positive when it flows clockwise and negative when it flows counterclockwise.
  2. How would your graph be different if the region on the left side of the applet had zero magnetic field instead of a field into the screen? Explain.
