Problem 29.5

Please wait for the animation to completely load.

The animation shows the cross section of a wire loop in a changing magnetic field (the wire loops out of and into the screen).  The graph shows the magnetic field in the x direction as a function of time (position is given in centimeters, time is given in milliseconds, 10^-3 s, and magnetic field strength is given in tenths of tesla, 10^-1 T).  Restart . 

1. Sketch a graph of the induced emf in the loop as a function of time. 
2. What is the maximum value of the emf? 
3. What is the direction of the current in the loop as a function of time (use the convention that current flowing out of the top of the loop is positive)?
