Magnetic Fields Prac Help

Hey guys

Just started Unit 4 and we did a prac relating to magnetic fields. I really dont understand theory though and I'm having a hard time answering the questions :/

If anyone would be able to show how to do some of the questions for the prac (I've uploaded), it would be really great.
Even if you just explain the theory behind it so I can do the questions myself, would be really helpful.

I've done question 1, but no idea on question 2, 3 and 4.
