1. The problem statement, all variables and given/known data I was given this question on a "practice final" and I have no idea how to approach it whatsoever...any help (particularly if you could walk me through it...physics isn't my forte...!) would be greatly appreciated! "Two long straight wires are oriented perpendicular to the page as shown in the diagram. The current in one wire is I1 = 3.0 A pointing into the page, and the current in the other wire is I2 = 4.0 A pointing out of the page. What is the magnitude of the net magnetic field at point P? Refer to the previous question. What is the direction of the net magnetic field at point P? Give your answer in degrees, measured CLOCKWISE from the positive x direction." (Please see figure attached) Thank you so, so much in advance for your help! 2. Relevant equations I honestly don't know (sorry!!) 3. The attempt at a solution I don't know where to begin (again, many apologies)!
