A single turn rectangular wire loop is placed next to a long straight wire. The loop and wire are in the plane of the page. Current I flows from left to right.

Is the loop CW$,$ CCW$,$ or zero if:

$1.$ The loop is at rest but current in the straight wire increases in magnitude. Explain?

$2.$ The current in the long straight wire is constant, but the loop is moved in the negative y direction. Explain?

$3.$ The current in the long straight wire is constant but the loop is moved parallel to the wire in the negative x direction. Explain?
