A circular loop of wire is positioned half in and half out of a square region of uniform \( \vec{B} \) field directed in the \( +z \) direction, out of the paper, as shown. To induce a counterclockwise current in this loop.
(a) Move it in the \( -x \) direction
(b) Move it along the \( +z \) axis, in the same direction as \( \vec{B} \)
(c) Move it in the \( +x \) direction
(d) Move it in the \( -y \) direction
