The Attempt at a Solution



Hello, well I think all I have to do is to calculate the two magnetic fields at this point, and then since they are going in opposite directions at this point find the difference. Is that correct?

I think I will also need to indicate the direction of the net magnetic field at this point, right?

Sounds like a plan.

As to direction yes I suppose they will want it given as out of the paper or into the paper.
 
ok great just wanted to be certain. BTW I stole the URL for the equation of the magnetic field due to a current carrying wire from another post. Is there a page on physics forums I can goto to copy and paste the URL's for equations in the future? it makes everything much tidier.
 
nvm i found it
