loser66 · Answer

the question is about the direction of the compass, why do you ask for the right hand rule?

idkwut · Answer

In class, there was a similar problem to this in which the teacher taught us the hand rule. I didnt get the change to ask him on more information because the bell rang at the last minute so I just thought we could use the hand rule to apply to this problem? @Loser66

the right hand rule applied to get the direction of: the magnetic field, the force of the magnetic field, the direction of the electric field.
Ok, if you want to apply the right hand rule. I guess!! the question is about the direction of the magnetic field

So then it would go... west? If the thumb is pointing up because of the current, the four left fingers will point to the west?

I think this is the trick question. No matter what direction of the current is, the compass ALWAYS  points to the north
