It would help if you told us exactly what you needed help with in each question. What don't you comprehend?

Well the answer for 5a is south to north and 5b is west but I don't know how the book came up with that answer. Also, in question 8 I chose an iron rod because it is a permanent magnet that's extremely strong for it's size, but I need conformation for my answer.

What does it say for the basic laws for current flowing through a wire?

Ah, but the iron rod ISN'T a permanent magnet! But what is it about iron that makes it good to use in an electromagnet? What does your book say about inserting rods into an electromagnet to form its core?
