Why are there more thumbtacks attached in electromagnet b as compared to electromagnet a?
I'm having a lot of trouble seeing the picture that goes along with this question in the book, so I'll have to take a wild guess based on no information. My guess is that electromagnet 'b' has more current flowing in its wire coil than electromagnet 'a' has. Another possibility is that the current through both coils is the same, but the coil of electromagnet 'b' is wound with more turns of wire than the coil of electromagnet 'a' is. It's just a guess. To be sure, I really need to see that picture.
