A rigid wire loop of square shape having side of length L and resistance R is moving along the x-axis with a constant velocity v_(0) in the plane of the paper. At t=0 , the right edge of the loop enters a region of length 3L where there is a uniform magnetic field B_(0) into the plane of the paper, as shown in the figure. For sufficiently large v_(0), the loop eventually crosses the region. Let x be the location of the right edge of the loop. Let v(x),I_(x) and F_(x) represent the velocity of the loop, current in the loop, and force on the loop, respectively, as a function of x. Counter-clockwise curren is taken as positive. Which of the following schematic plots (s) is are correct ? (Ignore gravity ) |
