(4) Consider an infinitely long wire oriented along the x-axis with current, I1 flowing in the -x direction. A square loop of wire with sidelength a is located next to this long wire such that the center of the square is at the point (d, -d,0). A circular loop of wire with radius a is located next to this long wire such that the center of the circle is at the point (-d, –d, 0). This setup is shown below. (a) The circular loop is slowly rotated about its axis. Is there current flowing in the circular loop? You don't need to specify the current direction. [2pts] (b) The square loop is slowly rotated about its axis. Is there current flowing in the square loop? You don't need to specify the current direction. [2pts] (c) The square loop is slowly moved in the +y direction. Is there current flowing in the square loop? If so, also specify which direction the current flows. [2pts]
