Homework Help: Magnetic field

  1. Nov 12, 2011 #1
    I attached the drawing. The problem state ment is to find the magnetic field at point P. the straight line segments cause no field. I have no problems with getting the numbers for this problem but I am confused about the direction. The solution manual says the field is out of the page, I don't understand why it's out of the page.

    Is it electron current, or is it conventional current?

    Sorry I don't know the difference between the 2 but if I had to guess it's electric current. I see similar problems with arc segments, I think the solution manual might be wrong for this one.
