A square loop with resistance R and side length 1 moves at constant velocity v and enters a region with a uniform magnetic field B directed out of the page. An external force ensures that the loop moves at the same velocity v at all times as the loop enters and exits the region with the magnetic field. 1 1 Find the magnitude and direction (clockwise or counterclockwise) of the induced current in the loop, as well as the total magnetic force on the loop, during the following time intervals: (a) (b) (c) After the front end of the loop has entered the magnetic field, but before the back end has entered the magnetic field. ; After the loop is completely engulfed by the magnetic field, but before it begins to leave the magnetic field. ) After the front end of the loop has left the magnetic field, but before the back end has left the magnetic field
