Answer #1

A. flux o t time b. Since , the flux in decreasing into the page . So, according to Lenz low the induced current would be such that the magnetic field due to this current minimises this change. So, using Right hand thumb rule, the direction of current is CLOCKWISE.

c. As we see from the graph of part a , the rate of change of flux increase with time and therefore the current will INCREASE with time.
