I made an educated guess when doing this but can someone explain the reasoning as to why it is correct and maybe an example where the answer would have been different?

We know by faraday equation, 
=> Current field is induced opposing the direction of flux change.
Here in this question, electric field inside the loop is increasing in direction pointing out of paaper, as loop is getting bigger.
Therefore, to oppose this change in flux current us induced in the loop such that magnetic field inside loop is pointing in to paper.
For the same, current should flow in the clockwise direction as per right hand thumb rule

In this problem, you will use Lenz's law to explore what happens when an electromagnet is activated a short distance from a wire loop. You will need to use the right-hand rule to find the direction of the induced current. When the switch is open, which of the following statements about the magnetic flux through the wire loop is true? Assume that the direction of the vector area of the wire loop is to the right. There is no magnetic...
