Answer
The current induced in circuit 2 is counterclockwise.
Work Step by Step
In part (a), we found that the magnetic field is directed into the page.
As the conducting bar moves, the area of the loop increases, so the flux into the page increases.
According to Lenz's law, the induced current will oppose this change, so the induced current produces a magnetic field directed out of the page.
According to the right hand rule, the current induced in circuit 2 is counterclockwise.
