Lenz's Law



Hello
Today I was covering Lenz's law in class. I was doing an example and I got all confused and couldn't get the current going the right way.

How do I figure out which way the induced current is going? I have looked in 4 books and they all use the same example. Haliday, Resnick, Walker use I different right hand rule..
the more I read and try to figure out the worse it gets....

Help Please
Tina (feeling dumb)
