21. A long straight wire is in the plane of a rectangular conducting loop. The straight wire initially carries a constant current i in the direction shown. While the current i is being shut off, the current in the rectangle is: A) zero B) clockwise C) counterclockwise D) clockwise in the left side and counterclockwise in the right side E) counterclockwise in the left side and clockwise in the right side 22. A circular loop of wire is positioned half in and half out of a square region of constant uniform magnetic field directed into the page, as shown. To induce a clockwise current in this loop: 1 loop A) move it in +x direction B) move it in +y direction C) move it in -y direction D) move it in - direction E) increase the strength of the magnetic field
