Yeah, because we all have the OAT Destroyer....
If you want someone to put in some effort to help, the least you can do is put in a little effort and post the question.

Okay for some reason my question did not get posted so I'll try again:
The question is #98 and it begins by showing you a picture of an arrow with current (I) pointing downwards, and next to it is another arrow of velocity pointing left. The velocity is negative.
The question asks: The magnetic field caused by this current:
a.) Points to the right
b.) Points in a counterclockwise direction
c.) Points in a clockwise direction
d.) Points to the left
e.) None of these
The answer is C. My question I guess is how do you work with the right hand rules? I haven't taken physics in a while and that seems to be the most confusing aspect of physics right now to me! Any help would be great!
and Dryeye: I tried contacting them several times but they never respond!

in this case, the velocity is unnecessary information. To use the right hand rule, just point your thumb in the direction of the current, I. as you curl your fingers around a particular point, that gives the direction of the magnetic field around it. if you are given v and r, the magnetic field can be found by pointing your fingers in the direction of v, and curling your fingers towards r. the direction that your thumb points is the magnetic field.

So I ignored the velocity and pointed my thumb downwards for the current (I) and curled my fingers. my fingers curled in and counterclockwise. The answer is clockwise so I'm still not getting it! 🙁
Sorry when i say downwards i mean in 2D not 3D where i am actually pointing to the floor. I am pointing downwards in the sense that the arrow on the paper is pointing towards the bottom of the page not to the floor.
