[SOLVED] Biot Savart homework question
What are the strength and direction of the magnetic field at point P in Figure P32.52, in which the current is 4.5 A and d = 2.2 cm?
Mu*I/(4R) <--- Magnetic field for a half loop at center of circle
I tried numerous things with this. I know that the straight wires contribute no field so I only had to work with the arcs. I knew that the total magnetic field faces away from you as the magnetic field from the closest wire is stronger and goes into the page. I am at my last submission for this homework problem, so it is a hit or miss =(. My teacher explained it quickly and my textbook does not elaborate too far into this law. I have been stuck on this for several hours already. Thanks in advance.
EDIT
I am in no hurry whatsoever. This homework isn't due till thursday and I already have all questions but this one done. Thank you again in advance and answer when it is most convenient for you.
