Awire bent with two (where the right angles are) is on the x-axis. the sides parallel to the y-axis run in the -y direction. a movable wire, parallel to the x-axis but not on the x-axis at any time, moves in the +y direction. if a magnetic field going in the -z direction baths the circuit, what is the direction of the induced current in the movable wire? right angles (forming a u-shape) sits in the xy-plane. the closed end
