Thank you for your help!
I confused the two equations, sorry.
My answers now:
A: -B
B: -(pi+1)B The current is NI, which is 2I? So the loop’s magnetic field is μ2I/2R= μI/R.
C: +(+pi-1)B The wires don’t meet, so the current stays the same?
D: +(2+1/2pi)B
E: +pi.B/2
F: +(1/4pi+1)B
G...
Homework Statement
The wires below are infinitely long and some of them are with loops and semi loops. The current I is constant. What is the magnetic field in point O, when R is the distance from it?

In F, E and H, the magnetic field exerted by the terminal infinitely long...
Thanks :)
How would you find the distance from point P to the particle q? I've thought of another way: maybe use a new variable such as x, and then subtract x from D, as in E=k * Q/x^2 ; distance from p= D-x?
I'm unsure.
