The figure below displays a circular loop of aluminum wire in a uniform magnetic field pointing into the page. The radius of the loop is 11.0 cm and the magnitude of the field is 0.170 T. You grab points A and B and pull them in opposite directions, stretching the loop until its area is nearly zero, taking a time of 0.180 s to do so.
