Answer:

1. Given: rising number of magnetic field lines downward through loop.

2. By Faraday's Law of Induction 1 above persuade current in loop.

3. By Ampere's Law encourage current produces new magnetic field BPIN through loop.

4. By Lenz's Law BPIN is rising (out of page) to cancel new downward magnetic field lines.

5. By right-hand rule for somewhat curly something straight induced current (referred to in step 2) must be counter clockwise as outlook from above to produce upward BPIN.
