**URGENT: Magnet Stuff...**

I have this quiz tommorrow on magnetism (not even sure if that's what it is, lol), but anyway, if someone could guide me with these problems (or at least one or something) below then I will greatly appreciate it!

There are four magnet diagrams that you need to draw the field and direction for:

1. First magnet is a north/south bar.

2. Second one is two south ends of a magnet close together.

3. Third is a wire with current.

4. Fourth is the wire but shown as if you were looking into the wire.

5. Find the force if there's 6 microcoulombs, 15 m/s, and 100 Teslas given.

(What I have so far for that one: First find the force, then at parallel which is just zero (the rule), and then at 30 degrees

F = qvBsin0. Am I right on this? What's the answer?)

6. There is a picture that shows a metal rod with wires looped around it. Label the north and south pole.

7. There are two magnets between a rod, maybe metal. The magnets poles are reversed on each side. You have some arrows showing magnetic field. The pole has a negative and positive end. You're suppose to draw an arrow for deflection...

(Right Hand Rule Stuff):

8. How do you determine the direction of force?

9. How do you determine the direction of velocity?
