- Magnetic field is going out of the page --> Current is ccw
- Magnetic flux is decreasing (because as the bar moves upward, the area is decreasing), therefore the induced current will combat it by moving ccw and magnetic field will be going out of the page aka increase the decreasing field.
Book solution: The induced current will be counterclockwise (ccw). As the bar moves upward through the constant-magnetic- field region, the area of the loop decreases, so the flux through the loop decreases. By Lenz's Law, any induced current will tend to oppose this decrease. A ccw current will create a stronger magnetic field inside the loop, tending to increase the flux.
