Ques:

Point out the direction of the current if any induced to flow in the loop by the changing magnetic field. (Describe is the loop as viewed from above.)

Answer:

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

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

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

4. By Lenz's Law BPIN is descending (into page) to make up for loss of downward magnetic field lines.

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